  • Patent number: 12025812
    Abstract: Multi-wavelength light is directed to an optic including a substrate and metasurface optical components deposited on a surface of the substrate. The metasurface optical components comprise a pattern of silicon dielectric resonators with nonperiodic gap distances between adjacent dielectric resonators. Incident light directed to the metasurface optical components is scattered and phase-shifted by the configuration of the gap distances and the widths and thicknesses of the dielectric resonators. Each dielectric resonator has a rectangular cross-section such that a first phase shift is imparted for a transverse-electric (TE) component of the incident light and a second phase shift is imparted for a transverse-magnetic (TM) component of the incident light.

  • Patent number: 12019238
    Abstract: An electronic device may include a display system for presenting images close to a user's eyes. The display system may include a display unit that directs light and an optical system that redirects the light from the display unit towards a user's eyes. The optical system may include an input coupler and an output coupler formed on a waveguide. The input coupler may redirect light from the display unit so that it propagates in the waveguide towards the output coupler. The output coupler may redirect the light from the input coupler so that it exits the waveguide towards the user's eyes. A light-redirecting element may be used to redirect edge light that would otherwise be outside of the user's field of view towards the user's eyes.

  • Patent number: 11966033
    Abstract: A system and method of generating white light for a projection system in a compact form factor using laser diodes, a reflection system, and a phosphor target. Light emitted from the laser diodes can be directed towards a region of the phosphor target, where the phosphor target is excited and emits light in a desired spectrum in all directions. Some emitted light is collected by a collection lens. The emitted light collected by the collection lens can be combined with light from the original laser diodes to create white light for use in the projection system. Light emitted in a direction away from the collection lens can be redirected to the collection lens by the reflection system that employs a curved reflector on one side of the phosphor target and a flat reflector on the opposite side of the phosphor target.
