Phase-space analysis has been widely used in the past for the study of optical resonant systems. While it is usually employed to analyze the far-field behavior of resonant systems, we focus here on its applicability to coupling problems. By looking at the phase-space description of both the resonant mode and the exciting source, it is possible to understand the coupling mechanisms as well as to gain insights and approximate the coupling behavior with reduced computational effort. In this work, we develop the framework for this idea and apply it to a system of an asymmetric dielectric resonator coupled to a waveguide.

Husimi功能，用于耦合光学谐振器

过去，相空间分析已广泛用于光学谐振系统的研究。尽管通常将其用于分析谐振系统的远场行为，但在此我们将重点放在其对耦合问题的适用性上。通过查看共振模式和激励源的相空间描述，可以了解耦合机制，并获得洞察力，并以减少的计算量来近似耦合行为。在这项工作中，我们为这一想法开发了框架，并将其应用于耦合到波导的非对称介质谐振器系统。
