Abstract : The photorefractive effect in semiconductor materials is attractive for processing low intensity near-infrared optical signals which are important for optical communication and optical computing. Photoinduced large nonlinearity in GaAs materials has been extensively studied in bulk material. A few is with optical waveguide of GaAs materials though the signal amplification in GaAs waveguide via two wavemixing has been proposed.
