TLDR
The random fluctuations of the cavity resonance occurring under TO chaos are found to trigger delayed spontaneous soliton generation after the laser scan ends, which could enable soliton excitation with slow laser tuning speed.Abstract:
We investigate, numerically and experimentally, the effect of thermo-optical (TO) chaos on soliton generation dynamics in microresonators. Numerical simulations that include the thermal dynamics show that the generated solitons can either survive or annihilate when the pump laser is scanned from blue to red and then stop at a fixed wavelength; the outcome is stochastic and is strongly related to the number of solitons generated. The random fluctuations of the cavity resonance occurring under TO chaos are also found to trigger delayed spontaneous soliton generation after the laser scan ends, which could enable soliton excitation with slow laser tuning speed. Stochastic soliton annihilation/survival, as well as delayed spontaneous soliton generation, is observed experimentally in a silicon-nitride microresonator.read more

TL;DR: In this article, the authors demonstrate mode-locked soliton microcombs generated around 2μm in a high-Q z-cut LN microring resonator and find that the intracavity photorefractive effect is still dominant over the thermal effect in the 2-μm region, which facilitates direct accessing soliton states in the red-detuned regime.
