  • Second-order nonlinear optics material, the devices using same and methods of preparing
    Patent number: 6623665
    Abstract: The present invention relates to nonlinear optical (NLO) materials, compositions thereof and NLO devices using polymeric matrices supporting a second order NLO material defined by the formula ED—B—EW  (I) where ED is an electron donating moiety, B is a bridging moiety, and EW is the electron withdrawing moiety (terminal acceptor group) defined by formula II, where C1 is a carbon atom linked through a double bond to a cyclic or an acylic carbon atom in the bridging moiety, and A1, A2, A3 or A4are the same or different from one another, each of which is an electron withdrawing group such as CN, COR, COOR, COOH or CH═C(R)2 where R is a C1-6 alkyl.

  • Thermally stable electro-optic device and method
    Patent number: 5708178
    Abstract: Novel acceptor-donor-acceptor and donor-acceptor-donor compounds for use in forming a thermally-stable electro-optic waveguide are disclosed. Also disclosed is a thermally stable waveguide material containing thermally stable acceptor-donor-acceptor or donor-acceptor-donor guest dipole compounds in a temperature-resistant polymer matrix. The waveguide has selected regions in which the net dipoles of the guest molecules are oriented, for electro-optic switching when an electric field is placed across these regions.

  • Polymer-optical liquid matrix for use as a lens element
    Patent number: 5684636
    Abstract: A polymer composition is provided for use as a liquid lens element in a compound lens designed to reduce chromatic aberration. The polymer composition (i) has an abnormal optical dispersion and (ii) is more easily fabricated into the compound lens than a conventional optical liquid. The composition contains an abnormal optical liquid characterized by an abnormal optical dispersion and a polymer component. The polymer is soluble in the optical liquid and is present in an amount effective to impart a viscosity that is at least an order of magnitude greater than that of the liquid alone at a selected temperature.

  • Thermally stable electro-optic device and method
    Patent number: 5414791
    Abstract: Novel acceptor-donor-acceptor compounds for use in forming a thermally-stable electro-optic waveguide are disclosed. Also disclosed is a thermally stable waveguide material containing thermally stable acceptor-donor-acceptor or donor-acceptor-donor guest dipole compounds in dissolved form in a polyimide matrix. The waveguide has selected regions in which the net dipoles of the guest molecules are oriented, for electro-optic switching when an electric field is placed across these regions.
