The ability to do this in a scalable fashion brings nanophotonic research into the realm of commercial technology. For example, metasurfaces achieve high optical performance in fractions of the thickness of traditional bulky optical components and can be designed for unique, custom functionalities. By expanding the design space beyond the metasurface regime and allowing for photonic designs in full three dimensions, we can further increase the degrees of freedom at our disposal. This new design space is complex and inherently involves multiply scattering structures. In order to efficiently search for good solutions, we use an inverse design procedure based on the adjoint variable method. Taking advantage of this large design space, we can computationally optimize multi-functional meta-optical devices that achieve novel functionalities in minimal footprints. We demonstrate wavelength splitting photonic filters with application to color filter arrays on modern-day image sensors. These filters are designed to replace absorbing filters and instead re-route colors to specific sensor locations, thus recovering previously lost transmission. We show that these devices work with a variety of realistic fabrication restrictions and demonstrate their abilities experimentally in the microwave regime where we can realize layered devices via simple techniques like 3D printing. Finally, we comment on potential future applications and avenues where inverse design can help solve inherently difficult engineering challenges in nanophotonics.", "doi": "10.1117/12.2569132", "isbn": "9781510637306", "publisher": "Society of Photo-Optical Instrumentation Engineers (SPIE)", "place_of_publication": "Bellingham, WA", "publication_date": "2020-08-21", "pages": "Art.

In recent years, development of low-weight miniature two-photon microscopes has been of great interest for in vivo imaging of brain activity. Limited by these mechanical constraints, most of the developed miniature two-photon microscopes utilize graded index objective lenses that usually have inferior optical characteristics compared to conventional refractive objective lenses. Dielectric metasurfaces, a recent category of diffractive optical elements with enhanced capabilities, have proven versatile in various applications ranging from lensing to holography and polarization control. Their ultrathin form factor and potentially extremely low-weight make them very attractive for applications with stringent size and weight constraints. However, despite their success in various types of microscopy and imaging applications, they have not been previously utilized for multi-photon fluorescence microscopy. The main barrier for using metasurface lenses in multi-photon microscopy arises from their large chromatic dispersion that effectively makes them single-wavelength. Here we will present a double-wavelength metasurface lens especially designed to have the same focal length at 820 and 605 nm, corresponding to the excitation and emission wavelengths of a certain fluorophore. After characterizing the poly-silicon metasurface lens at both wavelengths, we used it in a two-photon microscopy setup and demonstrated its capability to capture two-photon images qualitatively similar to images taken with a conventional objective lens. We will also discuss the effects of chromatic dispersion of the metasurface lens on its two-photon imaging performance.", "doi": "10.1117/12.2510596", "isbn": "9781510624986", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_publication": "Bellingham, WA", "publication_date": "2019-03-08", "pages": "Art.

Polarimetric imaging is the process of measuring the state of polarization of light over an extended scene. It has several applications ranging from remote sensing to biological and medical imaging because it provides various pieces of information about the light source or the objects with which the light has interacted. So far polarization cameras have been made using polarization filters, and therefore suffer from two major drawbacks. First, there is a theoretical 50% upper limit on the efficiency of devices based on polarization filters. Second, to fully determine the state of polarization, multiple layers should be integrated in order to make polarization filters for circular or elliptical polarization states. Here, we present a polarization camera made using dielectric metasurfaces that operates based on separating and focusing orthogonal polarization states instead of polarization filtering. This allows for overcoming both drawbacks of current polarization camera designs. At the core of the design lies the capability of dielectric metasurfaces to fully control the polarization and phase of light. This enables designing and fabricating superpixels that separate and focus orthogonal polarization states of light on adjacent pixels on an image sensor over a single metasurface layer. Using this technique we have demonstrated full-Stokes polarization cameras with experimental efficiencies surpassing 60%, and superpixel dimensions reaching 4.8 \u00b5m\u00d77.2 \u00b5m. We have also used this camera to form polarization images of custom-designed polarization targets.", "doi": "10.1117/12.2510543", "isbn": "9781510624986", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_publication": "Bellingham, WA", "publication_date": "2019-03-08", "pages": "Art.

We present an on-chip all-optical quantum memory at telecom wavelengths using a nanobeam photonic crystal cavity fabricated directly in erbium-167 doped yttrium orthosilicate. Using an atomic frequency comb protocol, we store coherent pulses for memory times as long as 10 \u00b5s, albeit with low efficiency. For shorter memory times, we achieve a memory efficiency of 0.4%, which is limited by the coupling rate between the resonator and the ensemble of ions.

In waveguide-based devices, the light engine constitutes a significant portion of the total volume and weight. Dielectric metasurfaces have in recent years been used to demonstrate various high performance optical elements like blazed gratings and wide field of view lenses with small thicknesses, high efficiencies, and little stray light. Here, we report our work on the design of a compact light engine based on multi-metasurface optics with wide fields of view, integrated with three monochrome \u03bc-LED displays for red, green, and blue. The metasurfaces image the \u03bc-LEDs on the prism or grating couplers. This design avoids an important shortcoming of \u03bc-LEDs and metasurface lenses, i.e., each work well for a single wavelength. As an example, we present a design for 532 nm, with over 3000 resolved angular points in an 8-mm-diameter field of view, and a total volume less than 0.65 cc (<2 cc for the three wavelengths). Limited by the total internal reflection region inside a waveguide with a 1.78 refractive index, the light engine can produce an image with over 1500x1500 points over a field of view slightly larger than 85\u00b0x85\u00b0 in air. To the best of our knowledge, this is the first proposal and demonstration of such a system and therefore opens the path towards exploring the potentials of the metasurface diffractive optics technology for compact AR headsets with enhanced optical capabilities.", "doi": "10.1117/12.2523720", "isbn": "9781510627468", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_publication": "Bellingham, WA", "publication_date": "2019-02-27", "pages": "Art.

These properties have made them one of the leading technologies in quantum optical memories and a promising candidate for optical-to-microwave conversion. To take advantage of the full bandwidth of the rare-earth ensemble, one must overcome the decoherence of a broadband collective excitation due to inhomogeneous broadening. To this end, techniques based on controllable rephasing, such as atomic frequency comb (AFC) or controlled reversible inhomogeneous broadening (CRIB) memories, have been developed with great success. Recently, an alternative method was proposed to suppress the decoherence of an inhomogeneous ensemble via strong coupling to a cavity, a phenomenon called cavity protection. This technique has been demonstrated in the microwave domain with an NV spin ensemble, but has not been demonstrated in the optical domain. Here, we demonstrate cavity protection in the optical domain at the single photon level using an ensemble of rare earths ions coupled to a nanophotonic resonator. The reduction in decoherence due to the cavity-protection effect enables transfer of ultrafast (~50 GHz) frequency qubits into the collective ion excitation and retrieval with 98.7% fidelity. Building on these results to transfer these excitations to long-lived spin states would enable broadband, on-demand quantum memories.

In this talk I present our progress towards developing on-chip quantum light-matter interfaces based on nanophotonic resonators fabricated in rare-earth-doped crystals known to exhibit the longest optical and spin coherence times in the solid state. We recently demonstrated coherent control of neodymium (Nd3+) ions coupled to yttrium orthosilicate Y2SiO5 (YSO) photonic crystal nano-beam resonator. The coupling of the Nd3+ 883 nm 4I9/2-4F3/2 transition to the nano-resonator results in a 40 fold enhancement of the transition rate (Purcell effect), and increased optical absorption (~80%) - adequate for realizing efficient optical quantum memories via cavity impedance matching. Optical coherence times T2 up to 100 \u03bcs with low spectral diffusion were measured for ions embedded in photonic crystals, which are comparable to those observed in unprocessed bulk samples. This indicates that the remarkable coherence properties of REIs are preserved during nanofabrication process. Multi-temporal mode photon storage using stimulated photon echo and atomic frequency comb (AFC) protocols were implemented in these nano-resonators.

A fundamental property of all diffractive devices is their negative chromatic dispersion: a diffractive grating always disperses light in the opposite order compared to a refractive prism made of a material with positive (normal) dispersion. Unlike refractive devices, chromatic dispersion in diffractive devices stems from geometrical features, and cannot be controlled via the intrinsic material dispersion. In addition to the always negative sign, the amplitude of diffractive chromatic dispersion is set only by the function of the device. For instance, the angular dispersion of a grating is always given by d\u03b8/d\u03bb=tan(\u03b8)/\u03bb (where \u03b8 is the deflection angle and \u03bb is wavelength), or the focal distance dispersion of a diffractive lens is given by df/d\u03bb=-f/\u03bb. Therefore, the chromatic dispersion of diffractive devices has always been set by their function (e.g. by the deflection angle for a grating or the focal distance for a lens), and could not be controlled separately. Here, we present our work on breaking this fundamental relation between the function and chromatic dispersion of diffractive devices using metasurfaces providing independent control over phase and group delays. We use a reflective dielectric metasurface to experimentally demonstrate gratings and lenses that have positive, zero, and extraordinary negative chromatic dispersion. Apart from its fundamental scientific value, this concept expands the applications of diffractive devices as it enables various types of chromatic dispersions. For instance, a special case would be a dispersionless lens operating over a wide bandwidth with the same focal distance.", "doi": "10.1117/12.2253726", "isbn": "9781510606678", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_publication": "Bellingham, WA", "publication_date": "2017-04-28", "pages": "Art.

They have enabled diffractive optical elements with enhanced functionalities and performance. Nevertheless, metasurface diffractive optical elements share many of the properties of regular diffractive optical elements. One of these properties is the response of diffractive elements to changing the angle of illumination: if the beam incident on a grating is rotated by an angle, all diffraction orders will rotate by corresponding angles in the same direction. More precisely, because of the constant grating momentum, the change in the sine of all diffraction angles will be equal to the change in the sine of the illumination angle. Many optical devices of interest, however, do not require this type of behavior, which makes their implementation using metasurfaces very challenging. For instance retroreflectors, which reflect light incident from any angle to the same direction, or collimators, that deflect light coming from any angle to a single given direction, do not follow the regular diffractive optics angular response. We investigate properties of single-layer metasurfaces that enable devices like retroreflectors and collimators. We show that such metasurfaces should have the ability to control the phase, as well as the derivative of phase with respect to angle.

Small size, low weight, planar form factor, and potential for low-cost manufacturing using semiconductor fabrication techniques are some of the main features that make metasurfaces ideal candidates for implementation of low-cost miniaturized optical systems. However, to become competitive for practical applications, metasurfaces should also offer specifications (e.g. efficiency, bandwidth, and wavefront error) comparable to their refractive counterparts. We have recently demonstrated diffraction-limited metasurface lenses with high efficiency using high refractive index nano-posts. Low numerical aperture (NA) metasurface lenses have more than 90% focusing efficiency, but the efficiency of the lenses with NA>0.5 decreases with increasing NA and drops to ~40% for NA=0.9, thus resulting in a trade-off between the NA and efficiency. Here we identify the main physical origin of this trade-off as the low transmission of large diameter nano-posts for transverse-magnetic (TM) polarized light incident at large angles, and show that the low transmission is caused by the excitation of undesired high order modes in these nano-posts. To overcome this issues, we present a novel approach for evaluating different metasurface designs in implementation of high NA metasurface components. The approach is based on adiabatic approximation of aperiodic metasurfaces by periodic gratings, and considers the effect of large deflection angles. Using the proposed design approach, we experimentally demonstrate more than 75% focusing efficiency for metasurface lenses with NA=0.7, and more than 70% deflection efficiency for 50-degree beam deflectors for unpolarized light at 915 nm.", "doi": "10.1117/12.2250391", "isbn": "9781510606678", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_publication": "Bellingham, WA", "publication_date": "2017-04-28", "pages": "Art.

The small mode volume of the cavity results in a peak atomic spectral density of <10 ions per homogeneous linewidth, suitable for probing single ions when detuned from the center of the inhomogeneous distribution. The high-cooperativity coupling of a single ion yields a strong signature (20%) in the cavity reection spectrum, which could be detected by our efficient SNSPD. We estimate a signal-to-noise ratio exceeding 10 for addressing a single Nd ion with its 879.7nm transition. This, combines with the AFC memory, constitutes a promising platform for preparation, storage and detection of rare-earth qubits on the same ship.", "doi": "10.1117/12.2251673", "isbn": "9781510606777", "publisher": "Society of Photo-Optical Instrumentation Engineers", "place_of_publication": "Bellingham, WA", "publication_date": "2017-02-20", "pages": "Art.

Nano-photonic resonators with high quality factors and small mode volumes are required for efficient on-chip coupling to the small dipole moment of rare-earth ion transitions. However, direct fabrication of optical cavities in these crystals with current nanofabrication techniques is difficult and unparallelized, as either exotic etch chemistries or physical milling processes are required. We fabricated hybrid devices by mechanically transferring a nanoscale membrane of gallium arsenide (GaAs) onto a neodymium-doped yttrium silicon oxide (Y_2SiO_5) crystal and then using electron beam lithography and standard III-V dry etching to pattern nanobeam photonic crystal cavities and ring resonator cavities, a technique that is easily adapted to other frequency ranges for arbitrary dopants in any rare earth host system.

This is owning to the long-lived electronic spin coherence and the capability for spin manipulation and readout of NV centers. The primitive operation is to create entanglement between two NV centers, based on schemes such as 'atom-photon entanglement' proposed by Cabrillo et al. To scale this type of scheme beyond two qubits, one important component is an optical switch that allows light emitted from a particular device to be routed to multiple locations. With such a switch, one has choices of routing photons to specified paths and has the benefit of improving the entanglement speed by entangling multiple qubits at the same time. Yield of the existing diamond cavities coupled with NV centers are inevitably low, due to the nature of randomness for NV placement and orientation, variation of spectral stability, and variation of cavity resonance frequency and quality factor. An optical switch provides the capability to tolerate a large fraction of defective devices by routing only to the working devices. Many type of switching devices were built on conventional semiconductor materials with mechanisms from mechanical, thermal switching to carrier injection, photonics crystal, and polymer refractive index tuning . In this paper, we build an optical-thermal switch on diamond with micro-ring waveguides, mainly for the simplicity of the diamond fabrication. The the switching function was realized by locally tuning the temperature of the diamond waveguides. Switching efficiency of 31% at 'drop' port and 73% at 'through' port were obtained.", "doi": "10.1117/12.2002631", "isbn": "9780819494047", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_publication": "Bellingham, WA", "publication_date": "2013-03-29", "pages": "Art.

The InAs quantum dots\nare well suited for quantum photonic applications because they have excellent quantum\nefficiencies, large dipole moments, and a variety of quantum states that can be optically\ncontrolled [24, 3].", "doi": "10.1017/CBO9780511998331.010", "isbn": "9781107012585", "publisher": "Cambridge University Press", "place_of_publication": "New York", "publication_date": "2012-08", "pages": "153-168" }, { "id": "authors:4nr0k-vtp48", "collection": "authors", "collection_id": "4nr0k-vtp48", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20120917-091232794", "type": "book_section", "title": "Towards Integrated Optical Quantum Networks in Diamond", "book_title": "Advances in photonics of quantum computing, memory, and communication V", "author": [ { "family_name": "Faraon", "given_name": "Andrei", "orcid": "0000-0002-8141-391X", "clpid": "Faraon-A" }, { "family_name": "Santori", "given_name": "Charles M.", "clpid": "Santori-C-M" }, { "family_name": "Huang", "given_name": "Zhihong", "clpid": "Huang-Z" }, { "family_name": "Acosta", "given_name": "Victor M.", "clpid": "Acosta-V-M" }, { "family_name": "Barclay", "given_name": "Paul E.", "clpid": "Barclay-P-E" }, { "family_name": "Fu", "given_name": "Kai-Mei C.", "clpid": "Fu-Kai-Mei-C" }, { "family_name": "Beausoleil", "given_name": "Raymond G.", "clpid": "Beausoleil-R-G" } ], "contributor": [ { "family_name": "Hasan", "given_name": "Zameer U.", "clpid": "Hasan-Z-U" }, { "family_name": "Hemmer", "given_name": "Philip R.", "clpid": "Hemmer-P-R" }, { "family_name": "Lee", "given_name": "Hwang", "clpid": "Lee-Hwang" }, { "family_name": "Santori", "given_name": "Charles M.", "clpid": "Santori-C-M" } ], "abstract": "We demonstrate coupling between the zero phonon line (ZPL) of nitrogen-vacancy centers in diamond and the modes of optical micro-resonators fabricated in single crystal diamond membranes sitting on a silicon dioxide substrate.

This permits a strong interaction of light and matter, which is relevant for construction of classical light sources with improved properties (e.g., low threshold lasers) and of nonclassical light sources (such as single and entangled photon sources), which are crucial pieces of hardware of quantum information processing systems. This talk will cover some of our recent experimental results on quantum and classical devices enabled by such interaction, as well as our work on designing such devices and circuits efficiently. We have demonstrated a spontaneous emission rate enhancement by a factor of 8 and suppression by a factor of 5 for a single self-assembled InAs/GaAs quantum dot (QD) embedded in a GaAs photonic crystal cavity and on- and off-resonance with the cavity mode, respectively. A strong localization of optical field in such a nanocavity (experimental Q-factor of 5000 and mode volume below a cubic optical wavelength) with a quantum dot embedded inside is of importance for building single photon sources with improved efficiency, photon indistinguishability, and repetition rate. We have demonstrated a single photon source on demand based on the pulsed excitation of a single quantum dot in such a nanocavity, with pulse duration between 200 ps and 8 ns and with a small multi-photon probability (as small as 5% compared to an attenuated laser of the same intensity). In addition, we have shown that colloidal PbS quantum dots coupled to AlGaAs photonic crystal cavities can be used as an alternative to self-assembled InAs/GaAs quantum dots for construction of cheap and reusable quantum and classical light emitters. We have also demonstrated an improved classical light source-laser, based on coupling of a large number (81) of photonic crystal nanocavities inside a two dimension- - al array. Such a laser exhibits a low lasing threshold (~2.5 mW), operates in a single mode, produces large output powers (greater than 12 muW, which two orders of magnitude larger than a single nanocavity laser), and can be directly modulated as speeds greater than 100 GHz. An inverse problem approach to designing photonic crystal cavities that we have developed enables their rapid optimization in a single step, thereby reducing the cavity optimization time from weeks to hours. We are also pursuing theoretical and experimental work on integration of a number of photonic crystal components (cavities and waveguides) into functional circuits for classical and quantum information processing, including nontrivial two-qubit quantum gates.", "doi": "10.1109/ICTON.2006.248243", "isbn": "1-4244-0235-2", "publisher": "IEEE", "place_of_publication": "Piscataway NJ", "publication_date": "2006-06", "pages": "75-76" } ]
