  • 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.
