Abstract:

In this paper, we successfully invented a polarization controlled light source for coherent or noncoherent fiber communication systems. The structure of our experiment includes 89C51 control board and feedback circuit which can stabilize states of polarization (SOPs) of output light. From the SOP modulation results, the given degree of polarization can be effectively controlled and the polarization state can be arbitrarily changed.

Keywords: Laser; polarization shift keying (PolSK); states of polarization (SOP); polarization mode dispersion (PMD); fiber communication systems
