Dissipative Kerr soliton microcombs in microresonators has enabled fundamental advances in chip scale precision metrology, communication, spectroscopy, and parallel signal processing. Here we demonstrate polarization diverse soliton transitions and deterministic switching dynamics of a self stabilized microcomb in a strongly coupled dispersion-managed microresonator driven with a single pump laser. The switching dynamics are induced by the differential thermorefractivity between coupled transverse magnetic and transverse electric supermodes during the forward backward pump detunings. The achieved large soliton existence range and deterministic transitions benefit from the switching dynamics, leading to the cross polarized soliton microcomb formation when driven in the transverse magnetic supermode of the single resonator. Resultantly the pump laser always exists at the effective blue detuning of the transverse magnetic resonance, fundamentally mitigating the thermal destabilization barrier and improving accessibility of the soliton formation regime. Subsequently and secondly, we demonstrate two distinct polarization diverse soliton formation routes arising from chaotic or periodically modulated waveforms via pump power selection. The generated self stabilized supermode microcomb features an extraordinarily large soliton existence range, a variety of soliton state transitions with well defined pump laser tuning, high pump microcomb conversion efficiency, and low repetition rate phase noise.

强耦合和自稳定微谐振器频率梳中的偏振分集孤子跃迁和确定性开关动力学

微谐振器中的耗散克尔孤子微梳使芯片级精密计量、通信、光谱学和并行信号处理取得了根本性进展。在这里,我们展示了由单泵浦激光器驱动的强耦合色散管理微谐振器中自稳定微梳的偏振不同孤子跃迁和确定性开关动力学。开关动力学是由耦合的横向磁超模和横向电超模在前向反向泵失谐期间的差分热折射率引起的。实现的大孤子存在范围和确定性跃迁受益于开关动力学,导致在单个谐振器的横向磁超模中驱动时形成交叉极化孤子微梳。结果,泵浦激光器始终存在于横向磁共振的有效蓝色失谐处,从根本上减轻了热失稳势垒并提高了孤子形成机制的可及性。随后和其次,我们通过泵浦功率选择展示了由混沌或周期性调制波形引起的两种不同的偏振不同孤子形成路径。生成的自稳定超模微梳具有非常大的孤子存在范围、具有明确泵浦激光调谐的各种孤子状态转换、高泵浦微梳转换效率和低重复率相位噪声。从根本上减轻热失稳势垒并提高孤子形成机制的可及性。随后和其次,我们通过泵浦功率选择展示了由混沌或周期性调制波形引起的两种不同的偏振不同孤子形成路径。生成的自稳定超模微梳具有非常大的孤子存在范围、具有明确泵浦激光调谐的各种孤子状态转换、高泵浦微梳转换效率和低重复率相位噪声。从根本上减轻热失稳势垒并提高孤子形成机制的可及性。随后和其次,我们通过泵浦功率选择展示了由混沌或周期性调制波形引起的两种不同的偏振不同孤子形成路径。生成的自稳定超模微梳具有非常大的孤子存在范围、具有明确泵浦激光调谐的各种孤子状态转换、高泵浦微梳转换效率和低重复率相位噪声。
