耦合非线性微腔中的共振自脉动

Resonant self-pulsations in coupled nonlinear microcavities

Victor Grigoriev, Fabio Biancalana

摘要:

本文对自脉动现象提出了一种新的观点,认为自脉动是由两个相互抵消的过程:模的拍频和模的转换所形成的平衡态。基于两个耦合的非线性微腔的结构提供了一个通用的例子,系统具有增强的能力,这种现象。提出了多层介质结构的具体设计方案,并应用耦合模理论描述了其动力学特性。强调了自脉动的频率与共振模式之间的频率分裂有关,并且可以在很宽的范围内调节。

英文摘要:

A novel point of view on the phenomenon of self-pulsations is presented, which shows that they are a balanced state formed by two counteracting processes: beating of modes and bistable switching. A structure based on two coupled nonlinear microcavities provides a generic example of system with enhanced ability to this phenomenon. The specific design of such structure in the form of multilayered media is proposed, and the coupled mode theory is applied to describe its dynamical properties. It is emphasized that the frequency of self-pulsations is related to the frequency splitting between resonant modes and can be adjusted over a broad range.
