  • Polymer guest-host systems and polymer electro-optic waveguide systems
    Patent number: 6978069
    Abstract: An electro-optic system in accordance with an embodiment of the present invention comprises a high glass transition temperature (Tg?about 210° C.) polymer matrix featuring aromatic groups on the backbone repeating unit, which hosts a guest, high hyperpolarizability organic NLO chromophore. Electro-optic systems according to embodiments of the present invention exhibit relatively high electro optical activity and low optical loss, and may exhibit optical stability at temperatures exceeding 70° C. Guest-host polymer systems in accordance with embodiments of the present invention may be formed into unique and appropriate shapes such as waveguides.
