A normal form for frequency combs and localized states in Kerr-Gires-Tournois interferometers
摘要：
我们阐明了垂直外腔Kerr-Gires-Tournois干涉仪中时间局域态和频率梳形成的机制。我们减少我们的第一原则模型的基础上延迟代数方程组的最小斑图形成的情况。它是一个由三阶色散和非线性漂移等高阶效应修正的实立方Ginzburg-Landau方程。后者负责通过锁定连接注入微腔的高强度水平和低强度水平的畴壁来产生局域态。我们解释的有效参数的正常形式与配置的光学设置。比较这两个模型，我们观察到一个很好的协议接近双稳态的发病。
英文摘要：
We elucidate the mechanisms that underly the formation of temporal localized states and frequency combs in vertical external-cavity Kerr-Gires-Tournois interferometers. We reduce our first principle model based upon delay algebraic equations to a minimal pattern formation scenario. It consists in a real cubic Ginzburg-Landau equation modified by high-order effects such as third order dispersion and nonlinear drift. The latter are responsible for generating localized states via the locking of domain walls connecting the high and low intensity levels of the injected micro-cavity. We interpret the effective parameters of the normal form in relation with the configuration of the optical setup. Comparing the two models, we observe an excellent agreement close to the onset of bistability.
