Paper Abstract

A simple etalon-type structure was considered as the basis for a light modulator. The distinction is made between thermally induced refractive index changes and the carrier injection mechanism. Experimental results are presented to demonstrate IR light modulation in a silicon etalon structure. The modulation is controlled by both current injection and visible light changing silicon's index. This modulator was used for coherent discrimination of low level cw laser illumination on a high irradiance incoherent background.
