Abstract

We experimentally demonstrate phase regeneration of a 40-Gb/s differential phase shift keying (DPSK) signal in a 1.7-m long highly nonlinear lead silicate W-type fiber using a degenerate two-pump phase-sensitive amplifier (PSA). Results show an improvement in the Error Vector Magnitude (EVM) and a reduction of almost a factor of 2 in the phase noise of the signal after regeneration for various noise levels at the input.

摘要

我们通过实验证明，在一根1.7米长的高度非线性硅酸铅W型光纤中，使用简并双泵浦相敏放大器（PSA）对40 Gb/s差分相移键控（DPSK）信号进行相位再生。结果表明，对于输入处的各种噪声水平，再生后信号的误差矢量幅度（EVM）有所改善，相位噪声降低了近一半。
