    Abstract: An optical phased array formed of a large number of nanophotonic antenna elements can be used to project complex images into the far field. These nanophotonic phased arrays, including the nanophotonic antenna elements and waveguides, can be formed on a single chip of silicon using complementary metal-oxide-semiconductor (CMOS) processes. Directional couplers evanescently couple light from the waveguides to the nanophotonic antenna elements, which emit the light as beams with phases and amplitudes selected so that the emitted beams interfere in the far field to produce the desired pattern. In some cases, each antenna in the phased array may be optically coupled to a corresponding variable delay line, such as a thermo-optically tuned waveguide or a liquid-filled cell, which can be used to vary the phase of the antenna's output (and the resulting far-field interference pattern).

    Abstract: A display for augmented reality (AR) includes an array of optical phased arrays (OPAs) integrated into a transparent substrate. The array of OPAs emit light encoded with four dimensional (4D) light field including 2D spatial coordinates and 2D directional coordinates to create an image of a virtual object on a retina of a viewer. By adjusting the emission directions of light beam emitted by individual OPAs in the display, the depth perception can be adjusted accordingly. The array of OPAs can also be encoded with holographic information, including intensity and phase distribution, of a virtual object to create the image of the virtual object on the retina. The AR display can further incorporate liquid crystal (LC) into the OPAs for modulating the amplitudes and relative phases of light emitted by the OPAs.

    Abstract: A frequency-chirped nano-antenna provides efficient sub-wavelength vertical emission from a dielectric waveguide. In one example, this nano-antenna includes a set of plasmonic dipoles on the opposite side of a SiYV4 waveguide from a ground plane. The resulting structure, which is less than half a wavelength long, emits a broadband beam (e.g., >300 nm) that can be coupled into an optical fiber. In some embodiments, a diffractive optical element with unevenly shaped regions of high- and low-index dielectric material collimates the broadband beam for higher coupling efficiency. In some cases, a negative lens element between the nano-antenna and the diffractive optical element accelerates the emitted beam's divergence (and improves coupling efficiency), allowing for more compact packaging. Like the diffractive optical element, the negative lens element includes unevenly shaped regions of high- and low-index dielectric material that can be designed to compensate for aberrations in the beam emitted by the nano-antenna.

    Abstract: It is provided an optical system for changing a spectral range of a cryogenically cooled detector. The optical system allows selective spectral transfer of radiation, and provides a reflecting field of view at an undesired range directed towards cold surfaces. A removable spectral filter having a high transmittance at a first spectral range and a low transmittance at a second spectral range is disposed outside a cold shield. A reflective surface faces the detecting device and provides the detector a reflecting field of view at the second spectral range directed towards the cold shield, and a blackened cold skirt thereof. Alternatively, a dichroic mirror is disposed inside the cold shield and has a high reflectance at a first spectral range and a high transmittance at a second range. The detecting device includes a first arm and a second arm of the cold shield to accommodate respective optical channels. A removable selective mirror having a high reflectance at the first spectral range is disposed outside the cold shield. A reflecting field of view at the undesired spectral range directed towards a blackened surface of the cold shield or a thermo-electric cooler is provided.
