Abstract

Polarization is one of the most fundamental property of Electromagnetic (EM) wave, which describes it completely. The study of polarization of light through Faraday Rotation Effect, rotation of plane of polarized wave when traveling through Terbium Gallium Garnet (TGG) crystals placed inside solenoid, subjected to a strong axial magnetic field can be a novel approach in communication. Experiment shows conversion of polarization modulated light into intensity modulated light, and phase shifted demodulated waveform w. r. t. input modulating signal. Insertion of properly matched and tuned circuit before coil and amplifier after demodulation leads to better reception of signal.
