Stability and non-linear dynamic analysis of Kerr optical frequencycombs in dual-coupled microcavities with high-order dispersion

We investigate the stability and nonlinear dynamics of Kerr optical frequency comb inside a dual coupled microcavity with high-order dispersion effect based on theoretical model Schrödinger equation. The effects different parameters evolution spectral characteristics field in cavity are also explored. Theoretical results indicate that addition third-order enlarges domain parametric space transforms periodically varying soliton breathers chaos into stable bright soliton. In order to obtain an accurate envelope, higher-order should be considered. Moreover, terms have significant comb, such as envelope shift dispersive wave position. Specifically, positive fourth-order can broaden spectrum enhance waves; while negative suppress generation symmetric comb; fifth-order regulate drift direction speed solitons. great value for regulation design studies double-coupled experiments.
