在比较皮秒脉冲产生技术之后，报告了用于多接触和传统单接触InGaAsP-InP激光器产生具有改进抖动的皮秒脉冲序列的反馈方案。采用一种新颖的光电反馈方案，实现了调q激光源的亚皮秒抖动。谐振电反馈的使用可以将增益开关脉冲的时序抖动提高6倍。脉冲到脉冲的时序抖动低至250秒演示了光和电的混合反馈方案。建立了光电、电学和光学反馈方案对二极管激光器时序抖动的限制，并首次比较了关键的皮秒脉冲产生方案的时序抖动。
Following a comparison of picosecond-pulse generation techniques, feedback schemes are reported for the generation of picosecond pulse trains with improved jitter for both multicontact and conventional single-contact InGaAsP-InP lasers. Subpicosecond jitter is achieved for Q-switched laser sources using a novel optoelectronic feedback scheme. The use of resonant electrical feedback is shown to improve the timing jitter of gain-switched pulses by up to six times. Pulse-to-pulse timing jitter as low as 250 fs is demonstrated for a hybrid of optical and electrical feedback schemes. Limits for timing jitter in diode lasers are established for optoelectronic, electrical, and optical feedback schemes, and the key picosecond pulse generation schemes are compared in terms of timing jitter for the first time.
