FARADAY ROTATION IN PHOTOREFRACTIVE InP:Fe

摘要

We report on the investigation of Faraday rotation (FR) of photorefractive(PR) indium phosphide (InP:Fe) conducted at several different wavelengths at room temperature. Appreciable FR, yielding Verdet constant values at 980, 1064, 1320 and 1550 nm at room temperature, has been observed. We have also investigated the role of excitation energy in FR for this class of materials. At wavelength of 980 nm and an applied magnetic field of 1.5 + -0.05 tesla, polarization rotation of 45 +- 1.0 degrees has been observed.
