  • Patent number: 10935719
    Abstract: An optical waveguide is formed on a support member. A second cladding layer is formed on a surface of a first cladding layer so as to cover a core layer. An opening is opened at the second cladding layer-side, penetrates the second cladding layer and the core layer, and closed at the first cladding layer-side. The opening has a first surface and a second surface ranging from the opened side to the closed side. In a vertical section taken along a longitudinal direction of the core layer, a first angle between a perpendicular line drawn from an opening end of the first surface to the surface of the first cladding layer and the first surface, and a second angle between a perpendicular line drawn from an opening end of the second surface to the surface of the first cladding layer and the second surface are all acute angles.

  • Patent number: 10929667
    Abstract: An augmented reality optical system comprises a waveguide structure that includes a waveguide layer supported by a substrate. An input grating and an output grating reside within the waveguide layer and are laterally spaced apart. Input light from a display is made incident upon the input grating. The input light is coupled into the waveguide layer and travels therein as multiple guided modes to the output grating. The input and output gratings provide phase matching so that the guided modes are coupled out of the waveguide layer by the output grating continuously along the output grating to form output light. Meantime, light from a scene is transmitted perpendicularly through the output grating so that the output light and the light from the scene are combined by the eye of a user to form an augmented reality image.

  • Patent number: 10921540
    Abstract: An optical fiber fan-out assembly includes multiple optical fibers arranged in a one-dimensional array in a transition segment in which spacing between fibers is varied from a first pitch (e.g., a buffered fiber diameter of 900 ?m) to a second pitch (e.g., a coated fiber diameter of 250 ?m). A polymeric material encapsulates the optical fibers in the transition segment, and the assembly further includes multiple optical fiber legs each terminated with a fiber optic connector. Optical fibers extending beyond a boundary of the polymeric material are subject to being mass fusion spliced to another group of multiple optical fibers, and the fusion splices encapsulated with polymeric material, to form a fiber optic cable assembly. Methods for fabricating multi-fiber assemblies providing fan-out functionality are further provided, and the need for furcation tubes is avoided.

  • Patent number: 10908357
    Abstract: In integrated optical structures (e.g., silicon-to-silicon-nitride mode converters) implemented in semiconductor-on-insulator substrates, wire waveguides whose sidewalls substantially consist of portions coinciding with crystallographic planes and do not extend laterally beyond the top surface of the wire waveguide may provide benefits in performance and/or manufacturing needs. Such wire waveguides may be manufactured, e.g., using a dry-etch of the semiconductor device layer down to the insulator layer to form a wire waveguide with exposed sidewalls, followed by a smoothing crystallographic wet etch.
