Research on Degenerate-Four-Wave-Mixing-Based All-Optical Reshaping Using Polarization Multiplexing
Abstract: According to the four wave mixing (FWM) process of three input light beams in highly nonlinear fiber (HNLF), the major crosstalk factors occurring in the FWM-based multi-wavelength all-optical regenerators are ana- lyzed. A new two-channel all-optical reshaping scheme based on degenerate FWM is proposed, in which the linear po- larization states of two high-power data light are orthogonal each other and are controlled at 45˚ relative to that of con- tinuous wave. It is shown by simulation that the non-degenerate FWM crosstalk components can be greatly suppressed by optimizing the HNLF birefringence and both the extinction ratio and Q-factor of regenerated signal are improved to a great extent.
