  • Luminaire having improved uniformity of output
    Patent number: 10119682
    Abstract: The invention provides a luminaire comprising an optical element configured to spread light uniformly across a full visible face of the luminaire. The optical element comprises a central region and an outer peripheral region, each configured to receive light emitted by a light source arrangement and to direct this light out through a respective region of the light exit area of the luminaire. The central region receives light through a central transmissive surface portion which partially bounds it across its top. A further reflective tapered portion of the central region acts to reflect light incident at either of its two opposing sides, and provides a mixing function both within the central region of the optical element and within an inner compartment of the luminaire which extends between the optical element and the housing.

  • Techniques for direct optical coupling of photodetectors to optical demultiplexer outputs and an optical transceiver using the same
    Patent number: 10042116
    Abstract: An arrayed waveguide grating (AWG) device for use in an optical transceiver is disclosed, and can de-multiplex an optical signal into N number of channel wavelengths. The AWG device can include an AWG chip, with the AWG chip providing a planar lightwave (PLC) circuit configured to de-multiplex channel wavelengths and launch the same into output waveguides. A region of the AWG chip may be tapered such that light traveling via the output waveguides encounters an angled surface of the tapered region and reflects towards an output interface region of the AWG chip. Thus detector devices may optically couple to the output interface region of the AWG chip directly, and can avoid losses introduced by other approaches which couple an output of an AWG to detectors by way of a fiber array or other intermediate device.
