  • Photo-induced dichroic polarizers and fabrication methods thereof
    Patent number: 8576485
    Abstract: A method of forming a polarizing material is provided including exposing a layer of dichroic material to activating light illumination to provide an ordered structure with a distinguished absorption axis and thus photo-induce polarization, and fixing the induced polarization by polymerization of the dichroic layer. Novel polarizing materials formed thereby are also provided. By selectively exposing regions of the dichroic material to differing activating radiation, different regions with different polarization axes can be created. The polarizing material can also be provided with a coating or coatings to alter the spectral responses, and a stack formed of a plurality if dichroic layers can be provided.
    Type: Grant
    Filed: September 28, 2010
    Date of Patent: November 5, 2013
    Assignee: The Hong Kong University of Science and Technology
    Inventors: Vladimir Markovich Kozenkov, Wing Chiu Yip, Vladimir Grigorievich Chigrinov, Hoi Sing Kwok

  • Photo-induced dichroic polarizers and fabrication methods thereof
    Patent number: 7070913
    Abstract: The present invention provides a method of forming a polarizing material comprising exposing a layer of dichroic material to activating light illumination to provide an ordered structure with a distinguished absorption axis and thus photo-induce polarization, and fixing the induced polarization by polymerisation of the dichroic layer. The present invention also provides novel polarizing materials formed thereby. By selectively exposing regions of the dichroic material to differing activating radiation, different regions with different polarization axes can be created. The polarizing material can also be provided with a coating or coatings to alter the spectral response, and a stack formed of a plurality if dichroic layers may be provided.
