A Method of Maintaining the Intensity Level of a Polarization Encoded Light Signal

Abstract

Optical signal has a strong role in parallelism. That is why, a strong effort to implement data processors with optics as information carrying signal instead of electronic signal is being supported in almost every corner of the world. In an optical system a logic state can be represented in different ways e.g. with the intensity level or with the polarization angle of the light signal. In long distance communication of optical signal the intensity of the signal may be reduced due to various reasons. Then the logic processor which operates on the basis of the intensity level encoding of the signal fails to work properly in the detecting side. In that situation we need to find out an alternative approach to maintain the intensity level of the light signal. In this communication the authors propose a new method to continue the intensity level of the light signal keeping the polarization of the beam unaltered.
