Summary
We investigated nonlinear dynamics in AlGaAs microresonators, observing localized states driven by thermal effects and electronic nonlinearities. Precursor cavity solitons were identified in this study.
Area of Science:
- Nonlinear optics
- Solid-state physics
- Materials science
Background:
- AlGaAs microresonators exhibit complex nonlinear optical phenomena.
- Understanding these dynamics is crucial for photonic device applications.
Purpose of the Study:
- To investigate the transverse nonlinear dynamics of AlGaAs microresonators.
- To explore the role of thermal and electronic nonlinearities.
- To identify localized states and precursor cavity solitons.
Main Methods:
- Gaussian beam excitation of bulk and multi-quantum well AlGaAs microresonators.
- Operation in the mixed dispersive and saturable absorptive regime.
- Analysis of transverse nonlinear dynamics.
Main Results:
- Observation of strongly localized states (bright or dark in reflection).
- Identification of thermally induced nonlinear mechanisms dressing electronic nonlinearities.
- Detection of precursor forms of cavity solitons.
Conclusions:
- Thermal nonlinearities play a significant role in AlGaAs microresonator dynamics.
