Abstract
Dissipative Kerr solitons offer a promising approach for integrated frequency comb sources. Although aluminum gallium arsenide (AlGaAs) exhibits ultrahigh nonlinearity, its strong thermo‐optic effect raises significant challenges for stable soliton generation. Triggerring solitons necessitates either cryogenic cooling or resonator engineering, imposing stringent requirements on operational environments, comb spacing, and bandwidth. In this work, thermal management in AlGaAs‐on‐insulator microresonators is addressed using an auxiliary laser. This approach effectively suppresses the adverse thermal resonance shifts, thus enabling room‐temperature soliton comb generation. Simultaneously, the residual thermal effects can be leveraged to expand the soliton existence range up to 37 GHz without active feedback. The scheme imposes no limitations on resonator parameters, facilitating the observation of near‐zero‐dispersion solitons. This broadens the exploration horizons on the AlGaAsOI platform. The extended soliton existence range ensures a stable and robust soliton operation, which is crucial for fully exploiting the ultra‐high effective nonlinearity and high optical quality factors exhibited by this platform. This advancement is poised to accelerate the practical deployment of AlGaAs frequency comb sources.
耗散克尔孤子为集成频率梳源提供了一种很有前途的方法。虽然砷化铝镓(AlGaAs)具有超高的非线性,但其强烈的热光效应对稳定孤子的产生提出了重大挑战。触发孤子需要低温冷却或谐振器工程,对操作环境,梳间距和带宽提出了严格的要求。在这项工作中,使用辅助激光器解决了AlGaAs - on -绝缘体微谐振器的热管理问题。这种方法有效地抑制了不利的热共振位移,从而使室温孤子梳的产生成为可能。同时,在没有主动反馈的情况下,可以利用残余热效应将孤子的存在范围扩大到37 GHz。该方案对谐振腔参数没有限制,便于观测近零色散孤子。这拓宽了AlGaAsOI平台的勘探视野。孤子存在范围的扩大保证了孤子运行的稳定性和鲁棒性,这对于充分利用该平台所表现出的超高有效非线性和高光学质量因子至关重要。这一进展有望加速AlGaAs频率梳源的实际部署。
