对基于增益透明半导体光放大器（GT-SOA）的全光开关键控（OOK）到二进制相移键控（BPSK）调制格式转换进行了仿真分析，其中GT-SOA用作全光相位调制器（PM）。利用GT-SOA的宽带动态模型对GT-SOA的相位调制效应进行了数值模拟，并利用差分相位Q因子对BPSK信号的质量进行了评价。分析了保持光注入对性能的改善，并考虑了OOK信号的非归零（NRZ）和归零（RZ）调制格式。
All-optical on-off keying (OOK) to binary phase-shift keying (BPSK) modulation format conversion based on gain-transparent semiconductor optical amplifier (GT-SOA) is simulated and analyzed, where GT-SOA is used as an all-optical phase-modulator (PM). Numerical simulation of the phase modulation effect of GT-SOA is performed using a wideband dynamic model of GT-SOA and the quality of the BPSK signal is evaluated using the differential-phase-Q factor. Performance improvement by holding light injection is analyzed and non-return-to-zero (NRZ) and return-to-zero (RZ) modulation formats of the OOK signal are considered.
