  • Patent number: 9405086
    Abstract: Organizer tray including a base wall and a receiving wall that is coupled to the base wall. The base and receiving walls extend parallel to each other along a lateral axis. The receiving wall extends away from the base wall along an elevation axis that is perpendicular to the lateral axis such that the base and receiving walls define a circuit channel. The receiving wall has a curved shape. The base and receiving walls are shaped to hold a flex circuit assembly within the circuit channel, in which the flex circuit assembly includes a fiber-routing substrate and corresponding segments of optical fibers that extend within the fiber-routing substrate. The base and receiving walls are configured to hold the fiber-routing substrate such that the fiber-routing substrate satisfies a bend radius of the optical fibers.

  • Patent number: 9377594
    Abstract: An optical connector includes a two-dimensional array of lenses to couple optical signals between an optical integrated circuit and an optical fiber. The optical connector has a total-internal-reflection or mirror surface that redirects light between lenses at different surfaces of the optical connector. The lens arrays collimate light directed toward the reflection surface and focuses light received from the reflection surface. The two-dimensional array and prism allows for a low-profile, high-density optical connector based on free space optical light propagation.

  • Patent number: 9372347
    Abstract: A display system comprises an optical waveguide and a light engine. The light engine generates multiple input beams which form a virtual image. An incoupling grating of the waveguide couples each beam into an intermediate grating of the waveguide, in which that beam is guided onto multiple splitting regions. The intermediate grating splits that beam at the splitting regions to provide multiple substantially parallel versions of that beam. Those multiple versions are coupled into an exit grating of the waveguide, in which the multiple versions are guided onto multiple exit regions. The exit grating diffracts the multiple versions of that beam outwardly. The multiple input beams thus cause multiple exit beams to exit the waveguide which form a version of the virtual image. One or more surfaces of the intermediate grating comprise surface variations such that a visible banding effect is eliminated from the version of the virtual image.
