  • Liquid crystal waveguide with sub-aperture light coupling
    Patent number: 11169426
    Abstract: A Liquid Crystal Waveguide (LCW) system can provide sub-aperture incoupling or outcoupling of light having an input wavelength and input beamsize defining an aperture characteristic of the system. A Liquid Crystal Waveguide (LCW) can include a generally planar LCW core to receive light via a light input zone for communication toward a light output zone. Sub-aperture interfacial light couplers can be planarly arranged in or parallel to the planar LCW core in the light input zone or the light output zone. Sub-aperture interfacial light couplers can include teeth, prisms, or facets, a photonic crystal metasurface, or a geometric-phased holograph (GPH)). Overall LCW thickness can be reduced, which can be helpful in space-limited applications or for reducing material costs.
