摘要

我们研究了在具有损耗和增益的被动腔中产生的诱导局域耦合模式。我们的模型基于线性耦合Lugiato-Lefever方程，其中高斯泵浦光束仅应用于一个模式。通过数值模拟，我们证明了自离焦系统能够支持伙伴场中局域平稳模式的形成。耦合强度、腔体衰减率、失谐效应以及泵浦光束的强度和宽度等关键参数决定了这些诱导模式的特性。

Inducing localized solutions via interaction in a self-defocusing system with localized pumping

We investigate the emergence of induced localized coupled modes in passive cavities with both loss and gain. Our model is based on linearly coupled Lugiato-Lefever equations, where a Gaussian pump beam is applied to only one mode. Through numerical simulations, we demonstrate that self-defocusing systems are capable of supporting the formation of localized stationary modes in the partner field. The characteristics of these induced modes are determined by key parameters, including coupling strength, cavity decay rate, detuning effects, and the pump beam's intensity and width.
