Abstract

We report the first demonstration of polarisation insensitive all-optical wavelength conversion (AOWC) for single wavelength channel 640 Gbit/s return-to-zero differential-phase-shift-keying (RZ-DPSK) signal and 1.28 Tbit/s polarisation multiplexed (Pol-Mux) RZ-DPSK signals using a 100-m polarisation-maintaining highly nonlinear fiber (PM-HNLF) in a polarisation diversity loop configuration. The AOWC is based on four-wave mixing in PM-HNLF. Error free performance is achieved for the wavelength converted signals. Less than 0.5 dB polarisation sensitivity is obtained.

摘要

我们报道了首次利用处于偏振分集环路配置的100米保偏高非线性光纤（PM-HNLF），对单波长通道640 Gbit/s归零差分相移键控（RZ-DPSK）信号以及1.28 Tbit/s偏振复用（Pol-Mux）RZ-DPSK信号进行偏振不敏感全光波长转换（AOWC）的演示。该AOWC基于PM-HNLF中的四波混频。实现了波长转换信号的无差错性能。获得了小于0.5 dB的偏振灵敏度。
