  • Structured silicon-based thermal emitter
    Patent number: 9793478
    Abstract: An optical radiation source produced from a disordered semiconductor material, such as black silicon, is provided. The optical radiation source includes a semiconductor substrate, a disordered semiconductor structure etched in the semiconductor substrate and a heating element disposed proximal to the disordered semiconductor structure and configured to heat the disordered semiconductor structure to a temperature at which the disordered semiconductor structure emits thermal infrared radiation.
    Type: Grant
    Filed: July 6, 2016
    Date of Patent: October 17, 2017
    Assignee: SI-WARE SYSTEMS
    Inventors: Yasser M. Sabry, Diaa Khalil, Tarik E. Bourouina, Momen Anwar

  • Aspherical optical surfaces and optical scanners
    Patent number: 9158109
    Abstract: Optical systems with aspherical optical elements are described. The aspherical optical elements have surfaces in which the in-plane radius of curvature spatially varies and the in-plane cross section surface profile is characterized in that the multiplication of the cosine of the incidence angle raised to a non-zero exponent by the in-plane radius of curvature varies less than twenty percent between any two points on the in-plane cross section surface profile.
    Type: Grant
    Filed: July 17, 2013
    Date of Patent: October 13, 2015
    Assignee: SI-WARE SYSTEMS

  • Integrated monolithic optical bench containing 3-D curved optical elements and methods of its fabrication
    Patent number: 9046690
    Abstract: An optical system, such as an integrated monolithic optical bench, includes a three-dimensional curved optical element etched in a substrate such that the optical axis of the optical system lies within the substrate and is parallel to the plane of the substrate.

  • System, method and apparatus for a micromachined interferometer using optical splitting
    Patent number: 8508745
    Abstract: A Mach-Zehnder MEMS interferometer is achieved using two half plane beam splitters formed at respective edges of a first medium. The first beam splitter is optically coupled to receive an incident beam and operates to split the incident beam into two beams, a first one propagating in the first medium towards the second beam splitter and a second one propagating in a second medium. A moveable mirror in the second medium reflects the second beam back towards the second beam splitter to cause interference of the two beams.
