数值仿真半导体光放大器(SOA)延迟干涉仪(DI)光判决门的功率传输曲线，给出在40 Gb/s速率以下SOA-DI光开关的再生特性，进行了10~40 Gb/s恶化信号的再生实验验证。由于SOA的交叉增益调制（XGM）极度依赖于载流子的恢复时间，在高速时，基于SOA的XGM效应的反逻辑信号存在明显的码型效应，提出基于SOA的瞬时交叉相位调制效应结合交叉增益压缩（XGC）效应的全光2R(再放大、再整形)再生方案，实现了100 Gb/s的归零（RZ）信号的全光2R再生。

Power transfer function of a 40-Gb/s 2R (re-amplification and reshaping) regenerator consisting of a semiconductor optical amplifier (SOA) and a delay interferometer (DI) is culculated numerically, and the regeneration performance of the SOA-DI optical gate for the degraded signals at 10~40 Gb/s is experimentally investigated. Because the cross gain modulation (XGM) effect in a SOA depends on the carrier recovery time, inverted logical signal based on XGM experiences severe pattern effect at XGM-SOA-cross gain compression (XGC) regenerator. A novel all-optical 2R regeneration scheme by combining the transient cross phase modulation and XGC effects in SOA is proposed and it successfully demonstrates all-optical 2R regeneration for 100-Gb/s return-to-zero (RZ) signal.
