  • Photo polymers and uses thereof
    Patent number: 4857426
    Abstract: This invention relates to dry processible photo polymers, a method for their production and uses thereof. The photo polymers are produced by selectively irradiating discrete zones of a precursor polymer by UV or visible light followed by thermal oxidation to create polymer films which have modified optical and surface relief properties. Such photo polymers can be used in a number of applications eg wave guiding.
    Type: Grant

  • Phase conjugate reflecting media
    Patent number: 4768846
    Abstract: This invention relates to the use of films of poly(acetylene) whether isotropic, of low crystallinity or oriented as a nonlinear phase conjugate reflecting medium. The principle can be applied to devices comprising phase conjugate mirrors, or use of such devices for degenerate four-wave mixing or for producing real time holograms. The resultant devices can be used in laser targetting, high speed image processing, optical communication and for power and image transmission.
