High-birefringence fiber effects on transmitted pulses and mitigated by pulses' reshaper

The transmission performance of Gaussian pulses over a high-birefringence fiber (HBF) has been studied. The Gaussian pulses are broken into a series of deformed pulses in the experiment. The simulation and transmission experiments were performed with HBF. The result of simulation is consistent with that of the experiment. Mitigation of birefringence effect by pulses reshaper, which is made of fiber Bragg grating (0.4 nm of 3 dB bandwidth) and high nonlinear dispersion shifted fiber (about  1 ps/nm km), has also been done. The badly distributed Gaussian pulses are restored well after the pulses' reshaper.
