  • Patent number: 9946034
    Abstract: A plug may be coupled with a cable and include a fiber ferrule extending from the plug. A biasing mechanism may be arranged to bias a cover toward a covered configuration in which the fiber ferrule is situated within an internal volume defined by the cover and away from an uncovered configuration in which the fiber ferrule is situated at least partially outside of the internal volume defined by the cover. Bristles or other blockers may be positioned along or within a boundary of the internal volume of the cover, may be arranged to block particulate entry through the blockers into the internal volume of the cover in the covered configuration, and may be movable to permit passage of the fiber ferrule through the blockers in response to movement of the cover between the covered configuration and uncovered configuration.

  • Patent number: 9939578
    Abstract: Planar lightwave circuits with a polymer coupling waveguide optically coupling a planar waveguide over a first region of a substrate to an optical component, such as a laser, affixed to a second region of the substrate. The coupling waveguide may be formed from a polymer layer applied over the planar waveguide and optical component such that any misalignment between the two may be accommodated by patterning the polymer into a waveguide having a first end aligned to an end of the planar waveguide and a second end aligned to an edge of the optical component. In embodiments, the polymer is photo-definable, such as a negative resist, and may be patterned through direct laser writing. In embodiments, the optical component is a thin film affixed to the substrate through micro-transfer printing. In other embodiments, the optical component is a semiconductor chip affixed to the substrate by flip-chip bonding.

  • Patent number: 9897892
    Abstract: A non-mechanical optical beam steering device includes one or more polarization gratings (PG) coupled to one or more Steerable Electro-Evanescent Optical Refractors (SEEOR). It provides the coarse steering advantage of the PG and also the continuous fine steering advantage of the SEEOR. The result is far less complexity, size, weight, and cost over the alternative non-mechanical beam steering approaches as well as considerably less complexity, size, weight, cost, scanning-time, and mechanical breakdown over the more traditional gimbaled mirrors commonly used.

  • Patent number: 9885836
    Abstract: A collimator lens 311 emits by converting a light signal from an optical fiber cable 20 to a collimated light, for example. The collimator lens 311 is retained in a plug housing 315 coupled to a reception side optical connector of the light signal. When the plug housing 315 is not coupled to the reception side optical connector, the pressing portion 313a sets the position of the collimator lens 311 at a position at which the emitted light signal has a predetermined divergence angle. When the optical connectors of the transmission side and the reception side are not connected, the light signal emitted from the optical connector of the transmission side is dispersed, and therefore emission of the light signal is prevented from giving a bad influence to a visual perception function or the like.

  • Patent number: 9857170
    Abstract: A waveguide apparatus includes a planar waveguide and at least one optical diffraction element (DOE) that provides a plurality of optical paths between an exterior and interior of the planar waveguide. A phase profile of the DOE may combine a linear diffraction grating with a circular lens, to shape a wave front and produce beams with desired focus. Waveguide apparatus may be assembled to create multiple focal planes. The DOE may have a low diffraction efficiency, and planar waveguides may be transparent when viewed normally, allowing passage of light from an ambient environment (e.g., real world) useful in AR systems. Light may be returned for temporally sequentially passes through the planar waveguide. The DOE(s) may be fixed or may have dynamically adjustable characteristics. An optical coupler system may couple images to the waveguide apparatus from a projector, for instance a biaxially scanning cantilevered optical fiber tip.
