We generate random numerical waveforms that mimic laser phase noise incorporating laser-resonance enhanced phase noise. The phase noise waveforms are employed in system simulators to estimate the resulting bit error rate penalties for differential quadrature phase shift keying signals. The results show that baudrate dependence of the bit error rate performance arises from laser-resonance phase noise. In addition, we show with supporting experimental results that the laser-resonance phase noise on the pumps in four-wave-mixing-based wavelength converters is responsible for large bit error rate floors.
我们生成随机数字波形,这些波形模拟了包含激光共振增强相位噪声的激光相位噪声。相位噪声波形被用于系统模拟器中,以估计差分正交相移键控信号所产生的误码率惩罚。结果表明,误码率性能的波特率依赖性源于激光共振相位噪声。此外,我们通过支持性实验结果表明,基于四波混频的波长转换器中泵浦光上的激光共振相位噪声是造成高误码率底限的原因。
