  • Publication number: 20190018167
    Abstract: Various controllers herein detect a remote object's change of position. A controller emits a laser through a laser emitter at the remote object and measures an intensity of light reflected back to the controller through a photosensor disposed in proximity to the laser emitter. The surface of the remote object comprises a retroreflective portion, which reflects most of the laser beam's light in the direction it came from. A change in the remote object's position is detected when the intensity of light measured is substantially different after altering a factor of the laser emitter, such as power state.

  • Publication number: 20190018177
    Abstract: A compound retarder that creates independent control of Re and Rth. This can be done by forming a three-layer compound retarder, including a pair of matched ?A-plates, combined with single +A-plate. The +A-plate is typically an MD-stretched film, with retardation that is specific to the in-plane requirements (Re) of the application. The pair of ?A-plates have their optic axes crossed, such that Re=0, with an optic axis aligned parallel to the +A-plate. A single retardation value for the ?A-plate can produce improved field-of-view performance over a broad range of Revalues, making it a very practical means of universal compensation. While Rthis typically associated with a single retarder, retarder stacks with a diverse range of optic-axis orientations can be considered to have a compound (or composite) Rth value (RthC). The three-layer compound retarder has the practical benefit of enabling field-of-view compensation across a broad range of normal-incidence polarization transformations.

The device is formed in a core layer and comprises a focusing structure (SF) capable of converting a light beam from a target mode of the first waveguide to a target mode of the second waveguide. The focusing structure comprises a plurality of trenches (T1-T4) made in the core layer to create a pseudo graded refractive index, itself able to convert the light beam from the target mode of the first waveguide to the target mode of the second waveguide. The scope of the invention extends to a photonic circuit comprising a single-mode waveguide, a multi-mode waveguide and a device according to the invention for coupling the single-mode waveguide to the multi-mode waveguide. The multi-mode waveguide can comprise a surface coupling network in order to allow for coupling with an optical fibre.

    Abstract: A method and device for interconnecting optical components, such as optical fibers and optical circuits, in a flexible, repeatable, and cost-effective manner. Two or more optical components are interconnected by a flexible optical circuit substrate bearing one or more embedded optical fibers with a lens at each end of each fiber. The flexible optical circuit may be incorporated into a housing bearing apertures for receiving the optical connectors of the optical components that are to be interconnected with the device. The lensed ends of the fibers embedded in the flexible optical circuit are positioned adjacent to the apertures for optically connecting to the fibers within the connectors installed in the apertures without conventional mating connectors disposed inside the housing.
