Abstract

Since microcavity Kerr soliton combs have spectrum which can exceed one octave, high repetition rate and potential for on-chip integration, the dissipative Kerr soliton generation in microresonators has been widely studied in recent years. Although microcavity soliton combs have been demonstrated in microcavities of different materials and shapes, it is still challenging for soliton generation due to positive thermal effects. In this paper, a sol-gel processed SiO₂-CaF₂ hybrid toroid microresonator is numerically investigated. Based on the calculation and simulation model we developed, this CaF₂ coated SiO₂ microresonator may avoid thermal effects and thermo-mechanical oscillations. Compared to organic coatings for thermal compensation in previous studies, it is a more promising platform for soliton generation.
