论文摘要
我们介绍了带有环腔的电信混合III-V-n-silicon的相时动力学的详细表征。我们探索各种操作方案，这是增益电流和可饱和吸收器偏置电压的函数。我们使用阶梯式 - 近差测量来量化光谱呼叫并重建脉冲包络。通过这种技术，我们能够确定近转化限制操作的制度，当更换饱和吸收器偏置电压时，我们评估梳子相位关系中模式锁定的降解。最后，我们介绍了杂交模式锁定操作中的相锁定的初步研究，并展示了变换限量的脉冲。
We present the detailed characterization of the phase dynamics of a telecom hybrid III-V-on-silicon passively mode-locked laser with a ring cavity. We explore the various regimes of operation as a function of gain current and saturable absorber bias voltage. We use a stepped-heterodyne measurement to quantify the spectral chirp and reconstruct the pulse envelop. With this technique we are able to identify regimes of near-transform-limited operation and we assess the degradation of mode-locking in the comb phase relationship when saturable absorber bias voltage is changed. Finally, we present a preliminary study of the phase-locking in hybrid mode-locked operation and demonstrate transform-limited pulses.
