摘要

本文对具有保守立方非线性和增益饱和非线性损耗的一维耦合光学谐振器链的动力学进行了分析和数值研究。谐振器特征频率对其指数的线性依赖性使得使用万尼尔-斯塔克态作为激光模式成为可能。数值模拟表明，共振频率与光强度的关系会严重影响万尼尔-斯塔克态的稳定性。为了解释观察到的基于万尼尔-斯塔克态的单色激光失稳现象，我们提出了一个简单的扰动理论，并与数值模拟中获得的数据进行了比较。

Kerr nonlinearity effect on the stability of Wannier-Stark states in active optical systems

The paper provides an analytical and numerical investigation of the dynamics of a one-dimensional chain of coupled optical resonators with conservative cubic nonlinearity and the gain saturated by nonlinear losses. The linear dependency of the resonator eigenfrequencies on their indexes makes it possible to use Wannier-Stark states as lasing modes. Numerical simulations have shown that the dependency of the resonant frequencies on the light intensity strongly affects the stability of Wannier-Stark states. To explain the observed destabilization of monochromatic lasing based on Wannier-Stark states a simple perturbation theory has been developed and compared with the data obtained in the numerical simulations.

期刊介绍： This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
