  • Sacrificial waveguide test structures
    Patent number: 9395488
    Abstract: Sacrificial optical test structures are constructed upon a wafer of pre-cleaved optical chips for testing the optical functions of the pre-cleaved optical chips. The sacrificial optical structures are disabled upon the cleaving the optical chips from the wafer and the cleaved optical chips can be used for their desired end functions. The test structures may remain on the cleaved optical chips or they may be discarded.
    Type: Grant
    Filed: December 8, 2014
    Date of Patent: July 19, 2016
    Assignee: OCLARO TECHNOLOGY LIMITED
    Inventors: Neil David Whitbread, Lloyd Nicholas Langley, Andrew Cannon Carter
  • Array comprising a plurality of adjustable optical devices
    Patent number: 9083144
    Abstract: An adjustable array includes a plurality of optical devices. Each adjustable array device has an optical light output therefrom and is configured whereby the corresponding optical lights of the plurality of optical devices have a predefined nonequivalent relationship relative to one another with respect to an output parameter. In response to a drive signal, the plurality of optical devices are further configured to adjust the corresponding optical lights with respect to the output parameter while substantially maintaining the predefined nonequivalent relationship.

  • Glare-elimination device for surgical microscopes
    Publication number: 20050063058
    Abstract: An adapter that attaches to a surgical microscope for holding the lens cover of a sterile drape at an angle relative to the scope's objective lens, so as to eliminate the reflection (glare) of illumination off the drape lens cover as light is directed through the surgical microscope to the field of view at the patient surgical site.
