OPTICAL SIGNAL RECEIVER, STOKES VECTOR PROCESSING CIRCUIT AND OPTICAL SIGNAL TRANSMISSION AND RECEPTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an optical signal receiver capable of demodulating the light accurately, a Stokes vector processing circuit and an optical signal transmission and reception system.;SOLUTION: An optical signal receiver for receiving an optical signal, includes: a photodetector for detecting the signal light of an optical signal thus received; a Stokes vector calculation circuit for calculating the reference Stokes vector of the optical signal, based on the information about the polarization state of the optical signal of the signal light thus detected; and a reference Stokes vector update circuit for changing the reference Stokes vector thus calculated corresponding to polarization fluctuation of the optical signal, so as to follow the polarization fluctuation of the optical signal.;COPYRIGHT: (C)2015,JPO&INPIT
