  • Photocrosslinked second order nonlinear optical polymers
    Patent number: 5484821
    Abstract: A novel photocrosslinkable polymeric system has been developed for processing into films having stable second-order nonlinear optical properties. In the present system, polymers bearing photo-crosslinkable chromophores, such as polyvinylcinnamate and are reacted with appropriately designed nonlinear optical molecules with the cinnamate or other photocrosslinkable functionalities for photocrosslinking at one, two or more points. The system can be poled and photocrosslinked in the poled state to yield a material with stable optical nonlinearity and large electro-optic coefficients.
    Type: Grant
    Filed: February 7, 1994
    Date of Patent: January 16, 1996
    Assignee: University of Lowell
    Inventors: Braja K. Mandal, Sukant K. Tripathy, Jan-Chan Huang, Jayant Kumar
