Abstract :
A Cd1-xMnxTe(CMT) fiber optic magnetic field sensor has been developed with the use of a laser ablation deposition technique. The authors have investigated the Faraday effect in Cd1-xMnxTe thin films grown by the laser ablation deposition process. This method of growth yields high quality material, and, due to the low-temperature deposition, it enables integration of CMT in optoelectronic systems. A disk-shaped sensor structure, of diameter and thickness less than 3 mm and 75 μm, respectively, was incorporated in a fiber optic system. A linear response of the sensor has been tested in the magnetic field up to 0.8 T
