Paper Abstract

These photoconductive devices operate with c.w. Nd-YAG laser and use Joule effect enhanced nonlinearity, associated with the sharp angular resonance corresponding to the TEo guided mode excitation in a SOS (Silicon On Sapphire) film. Transfer characteristics and spatial uniformity of the transmitted beam for devices of various geometries have been measured and contrasted characteristics have been observed locally. Potential interest of these devices is discussed.
