摘要:

阻尼驱动的非线性薛定谔方程(NLSE)已被用于理解各种系统中的一系列物理现象。研究这一方程的背景下的光学超参量振荡器中的非线性色散耗散腔,其中NLSE通常被称为Lugiato-Lefever方程(LLE),我们导致一个新的,减少非线性振荡器模型,揭示了本质的自发创建尖锐的尖峰脉冲在光学谐振腔。我们确定了该模型的吸引解,它们对应于稳定的腔孤子和图灵斑图,并研究了它们的稳定程度。简化模型体现了模式同步和时空斑图形成之间的基本联系,并代表了一类新的自同步过程,其中非线性振子之间的耦合是由能量和动量守恒。

英文摘要:

The damped driven nonlinear Schrödinger equation (NLSE) has been used to understand a range of physical phenomena in diverse systems. Studying this equation in the context of optical hyper-parametric oscillators in anomalous-dispersion dissipative cavities, where NLSE is usually referred to as the Lugiato-Lefever equation (LLE), we are led to a new, reduced nonlinear oscillator model which uncovers the essence of the spontaneous creation of sharply peaked pulses in optical resonators. We identify attracting solutions for this model which correspond to stable cavity solitons and Turing patterns, and study their degree of stability. The reduced model embodies the fundamental connection between mode synchronization and spatiotemporal pattern formation, and represents a novel class of self-synchronization processes in which coupling between nonlinear oscillators is governed by energy and momentum conservation.
