| 摘 要： | 采用半导体光放大器(Semiconductor Optical Amplifier, SOA)的分段模型，对基于SOA光纤环镜的非归零 (Non-Return-to-Zero, NRZ)信号时钟分量提取进行了数值模拟.SOA光纤环镜可以将NRZ信号转化为包含其时钟分量的伪归零(Pseudo-Return-to-Zero, PRZ)信号给出了2.5Gb/s下的模拟计算结果，并与实验结果进行了比较，进一步给出了10Gb/s下的模拟计算结果.

| Abstract: | Clock component extraction of NRZ (Non-return-to-zero) signal based on SOA (semiconductor optical amplifier) loop mirror was numerically simulated using a multi-section model of SOA. The original NRZ signal can be converted to the corresponding PRZ (Pseudo-return-to-zero) signal that contains the same clock component. Simulation result of 2.5 Gb/s operation was given and was compared to the experimental result. Simulation result of 10 Gb/s operation was also given. |
