Abstract
Experimentally, investigation of nonlinear polarization evolution induced by cross phase modulation in optical fiber and its impact on transmission link are circumstantiated in this letter. We experimentally demonstrate that the use of 500-m length of highly non-linear fiber readily allows for our novel approach of implementing high-speed format transformation from return-to-zero amplitude-shift keying (RZ-ASK) to return-to-zero frequency-shifting keying (RZ-FSK) at 40Gb/s and above based on cross-phase-modulation-induced polarization rotation. The high-performance feasibility is verified and the operating parameters are achieved.
