Polarization insensitive wavelength conversion based on four-wave mixing for polarization multiplexing signal in high-nonlinear fiber
ABSTRACT We have theoretically and experimentally investigated polarization insensitive of all optical wavelength conversion for polarization multiplexing signal based on four-wave mixing (FWM) in nonlinear optical fiber. Optical polarization multiplexing technique can be used to double the transmission bit rate by adding data on each of two orthogonal optical states. At the receiver side, the two orthogonal signals can be obtained by direct detection. The eye diagrams of the original signals have been probed and compared with the converted one in this experiment. The characteristics of the converted signal have been fully studied and a little crosstalk which leads a better corresponding eye diagram has been obtained after polarization demultiplexing.

ABSTRACT: The advantages of fiber waveguides over bulk nonlinear media are demonstrated. A review is given of the main nonlinear effects which occur during propagation of laser radiation in fiber waveguides. The most interesting applications of nonlinear fiber optics are discussed.3 edited by Kelley, Paul L. and Kaminow, Ivan P. and Agrawal, Govind P., 01/2001; Academic Press., ISBN: 0120451433
