我们研究了在不同色散状态下泵浦的晶体回音壁模式盘谐振器中空腔孤子的形成。在傅立叶域中，这些耗散结构对应于特定类型的锁模克尔光学频率梳。根据二阶色散的符号和泵浦条件，我们表明可以出现亮腔孤子或暗腔孤子，并且我们表明这两种状态与可以通过实验区分的特征光谱特征相关。我们使用 Lugiato-Lefever 时空形式主义来研究导致这些方位孤子形成以及图灵模式出现的时间动力学。理论结果与使用在 1550 nm 附近泵浦的氟化钙和氟化镁盘谐振器获得的实验测量结果非常吻合。
We investigate the formation of cavity solitons in crystalline whispering-gallery-mode disk resonators that are pumped in different dispersion regimes. In the Fourier domain, these dissipative structures correspond to specific types of mode-locked Kerr optical frequency combs. Depending on the sign of the second-order chromatic dispersion and on the pumping conditions, we show that either bright or dark cavity solitons can emerge, and we show that these two regimes are associated with characteristic spectral signatures that can be discriminated experimentally. We use the Lugiato-Lefever spatiotemporal formalism to investigate the temporal dynamics leading to the formation of these azimuthal solitons, as well as the emergence of Turing patterns. The theoretical results are in excellent agreement with experimental measurements that are obtained using calcium and magnesium fluoride disk resonators pumped near 1550 nm.
