我们展示了一种据我们所知新颖的全光信号控制技术，基于双折射光纤中超短孤子脉冲的脉冲捕获和放大，以实现三个功能：放大、整形和重定时。信号和控制脉冲相互捕获并在光纤中共同传播。信号脉冲通过超短控制脉冲经历拉曼增益和孤子效应。通过实验和数值研究了这些特性。在 140 m 长的光纤中获得的最大增益为 28 dB。输出波形为~300 fs、无啁啾、sech2 形、超短脉冲。初始信号中±0.4 ps 内的延迟和提前得到了补偿。
We demonstrated an all-optical signal control technique, novel to our knowledge, based on pulse trapping and amplification by ultrashort soliton pulse in a birefringent fiber to implement three functions: amplification, reshaping, and retiming. The signal and control pulses trap each other and copropagate in the fiber. The signal pulse experiences Raman gain and soliton effect by an ultrashort control pulse. The characteristics were investigated both experimentally and numerically. The maximum gain obtained was 28 dB in a 140 m long fiber. The output waveforms were ∼300 fs, chirp-free, sech2-shaped, ultrashort pulses. Delays and advances within ±0.4 ps in the initial signal were compensated for.
