摘要： A metalens and an optical system having the metalens. The metalens includes: a substrate capable of transmitting light in different wavelength bands; and a plurality of unit cells on the same surface of the substrate. The multiple unit cells are arranged in an array, the unit cells are regular hexagons and/or squares. A center position of each unit cell or each of the center position and vertex positions of each unit cell is provided with a nanostructure. The nanostructures are symmetrically arranged with respect to a first axis and a second axis respectively, and partial nanostructures obtained by dividing the nanostructures on the metalens along the first axis and the second axis are identical to each other. The first axis is perpendicular to the second axis, and both the first axis and the second axis are perpendicular to a height direction of the nanostructures.

摘要： Manufacturing an optical device includes providing a substrate (102) having a polymeric layer (104) on a surface of the substrate, forming openings in the polymeric layer, and depositing a material in the openings to form meta-atoms (114, 214) of a first metastructure. Adjacent ones of the meta-atoms are separated from one another by polymeric material of the polymeric layer. Optical devices that include one or more metastructures in which meta-atoms are separated from one another by polymeric material are described, as are modules that incorporate the optical devices.

摘要： A method for preparing a stack of dielectric layer on a substrate. A substrate is provided and a first layer of liquid is printed onto a surface of the substrate. A first dielectric layer is formed by solidifying the first layer of liquid and a second layer of liquid is printed onto the first dielectric layer. A second dielectric layer is formed by solidifying the second layer of liquid. The liquid includes dielectric constituents and the liquid is printed such that droplets having a volume of less than one hundred nanoliters are locally deposited per square millimeter on the surface of the substrate.

摘要： A sub-hogel configuration for a high-definition light field display that can be used in the design of optical device and three-dimensional light field display technology. Three-dimensional holographic pixels (hogels) composed of monochromatic sub-hogels and a designed metasurface act as a directional optical element for a light field display. The sub-hogel structure design and method is suited for an achromatic metasurface to provide directional pixels for multiple view light field colored displays.

摘要： A see-through reflective optical device includes: a reflective metasurface configured for a targeted design optical wavelength, wherein the reflective metasurface comprises a sub-wavelength periodic arrangement of meta-atoms formed by patterned isolated gap surface plasmon (GSP) resonators, where the patterned isolated GSP resonators comprise a patterned optically thin metal layer for the design wavelength, an optically thick metal layer for the design wavelength, and an insulator layer between the patterned optically thin metal layer and the optically thick metal layer; and an array of apertures of random positions and diameters greater than the targeted design wavelength formed through the reflective metasurface providing a designed percentage of light transparency through the reflective metasurface. The reflective metasurface of the see-through reflective optical device may comprise, e.g., a reflective diffraction grating metasurface, and may be used as a combiner element surface in a near eye display assembly.

摘要： An example optical transceiver system, such as a solid-state light detection and ranging (lidar) system, includes a tunable, optically reflective metasurface to selectively reflect incident optical radiation as transmit scan lines at transmit steering angles between a first steering angle and a second steering angle. In some embodiments, a feedback element, such as a volume Bragg grating element, may lock a laser to narrow the band of optical radiation. A receiver may include a tunable, optically reflective metasurface for receiver line-scanning or a two-dimensional array of detector elements forming a set of discrete receive scan lines. In embodiments incorporating a two-dimensional array of detector elements, receiver optics may direct optical radiation incident at each of a plurality of discrete receive steering angles to a unique subset of the discrete receive scan lines of detector elements.

摘要： A metalens-integrated optical engine includes a plurality of light source modules, a collimating and deflecting module and a light-combining module. Each of the light source modules emits a light beam. The collimating and deflecting meta optical members is for collimating and deflecting the light beams such that the light beams are collimated and deflected and travel to a predetermined position. The light-combining module includes a light-combining meta optical array that is located at the predetermined position, that receives the light beams via the collimating and deflecting module, and that deflects the light beams, so as to combine the non-parallel light beams into a single light beam.
