摘要

We describe an all-optical wavelength conversion scheme for 1310 nm to 1550 nm based on nonlinear polarization rotation in a gain-transparent semiconductor optical amplifier (GT-SOA) which brings in the assistant light to improve the property of the converted light.From the SOA carrier density equations,the 1310 m-to-1550 nm wavelength conversion scheme is analyzed by the Jones matrix.The phase shift between TE and TM modes and the converted light are simulated at bit rate of 30 Gbit/s.We also analyze the influence of the input signal power,the injected current and the assistant light power on the extinction ratio of the converted light.
