  • Lithographic and measurement techniques using the optical properties of biaxial crystals
    Patent number: 7541600
    Abstract: A method and apparatus for accurately retrieving the position of an optical feature. The method uses the optical properties of biaxial crystals to conically refract the optical feature and transform the image of the optical feature to a circular ring structure. The position of the optical feature is then calculated by locating a center point associated with the circular ring structure.
    Type: Grant
    Filed: July 14, 2006
    Date of Patent: June 2, 2009
    Assignee: The Regents of the University of California
    Inventors: Daniel Neuhauser, Gabriel Y. Sirat
  • Crystal grating apparatus
    Patent number: 7515262
    Abstract: Apparatus for analyzing light having at least one wavelength, the apparatus comprising: (a) a light deflector for deflecting the light so as to provide a deflected light beam characterized by at least one wavelength-dependent angle, respectively corresponding to the at least one wavelength of the light; (b) an encoder, capable of encoding the deflected light beam so as to provide an encoded light beam characterized by at least one angle-dependent polarization state, respectively corresponding to the at least one wavelength-dependent angle; and (c) a decoder, for decoding the encoded light beam so as to determine at least one spectral component of the light.

  • Sub-carrier generation for optical communication
    Publication number: 20040208644
    Abstract: An optical transmitter, consisting of a radiation source which is adapted to generate a base optical beam with a base wavelength. The transmitter further consists of at least one modulator which is coupled to modulate the base optical beam so as to generate multiple carrier beams at respective side-bands of the base wavelength and to introduce information into the carrier beams for transmission thereby to a receiver.
