Single solitons and intermode breathing solitons in MgF₂ microresonators

Abstract

Intermode breathers can be triggered by the avoided mode crossings in microresonators. Here, we numerically and experimentally explore the breather and single soliton regimes as the pump-power and pump-cavity detuning vary. Below a pump-power threshold, a single soliton regime is obtained within a detuning range. Above this threshold, an intermode breather section emerges, resulting in a soliton-breather-soliton pattern in which the system transits from a stable soliton to a breathing soliton and back to a stable soliton as the detuning increases.
