Meng Xiaojun, Yan Lianshan, Yi Anlin, et al. High nonlinear fiber-based all-optical RZ to NRZ format conversion[J]. 2010,(6):1-3. DOI: 10.13756/j.gtxyj.2010.06.011.
We numerically analyze all-optical RZ to NRZ format conversion based on the Cross-Phase Modulation(XPM) in Highly Nonlinear Fiber(HNLF) and discuss the duty cycle of the RZ signals and the effects of the Q factor of fiber dispersion on the converted NRZ signals.Simulation results show that related higher Q factor can be obtained by carefully selecting the duty cycle of the input RZ signal and decreasing the dispersion difference between the RZ signal and continuous probe light.
