  • Photorefractive thin film polymer waveguide two beam coupling (WTBC) device
    Patent number: 5724460
    Abstract: A photorefractive polymer waveguide is used to perform waveguide two beam coupling. Light incident on the waveguide interferes with scattered incident light or an input signal to create a modulated index pattern in the waveguide. The incident light is diffracted by the modulated index pattern to amplify signals in the waveguide in the direction of signal propagation.
