微谐振腔中短寿命耗散克尔孤子态的稳态化
Bringing short-lived dissipative Kerr soliton states in microresonators into a steady state
摘要：
最近在光学微谐振器中产生了耗散克尔孤子，使微波重复率下的超短光脉冲成为可能，构成了相干和数值可预测的克尔频率梳。然而，时间孤子的播种和激发与腔内功率的变化相关联，这可能导致在激发过程期间的大的热共振位移，并使最常用的谐振器平台中的孤子状态短暂。在这里，我们描述了一种“功率踢”的方法来克服这种不稳定性，通过调制泵浦激光的功率。快速调制触发孤子形成，而功率的缓慢调节补偿激发激光扫描期间的热效应。使用这种方法，最初也非常短的寿命（100 ns）的孤子状态，遇到的SiN集成的光子微谐振器，可以被带入一个稳定的状态相比，早期报道的技术，依赖于调整的激光扫描速度只。一旦孤立子状态处于稳定状态，它可以持续数小时，并且是热自锁的。
英文摘要：
Dissipative Kerr solitons have recently been generated in optical microresonators, enabling ultrashort optical pulses at microwave repetition rates, that constitute coherent and numerically predictable Kerr frequency combs. However, the seeding and excitation of the temporal solitons is associated with changes in the intracavity power, that can lead to large thermal resonance shifts during the excitation process and render the soliton states in most commonly used resonator platforms short lived. Here we describe a "power kicking" method to overcome this instability by modulating the power of the pump laser. A fast modulation triggers the soliton formation, while a slow adjustment of the power compensates the thermal effect during the excitation laser scan. With this method also initially very short-lived (100ns) soliton states , as encountered in SiN integrated photonic microresonators, can be brought into a steady state in contrast to techniques reported earlier which relied on an adjustment of the laser scan speed only. Once the soliton state is in a steady state it can persist for hours and is thermally self-locked.
