腔体输入输出问题的回路理论
A loop theory for the input-output problems in cavities
摘要：
输入输出理论是研究光腔对外部激励响应的基础。现有的理论通常处理的是只有一个内模的腔系统。然而，人们对更复杂系统，特别是混合腔-物质系统越来越感兴趣，混合腔-物质系统包含至少两个内模，一个或多个分别来自光学腔和物质。在这里，我们提出了一个图形回路理论来计算和可视化的反射和透射光谱的多模腔，类似的费曼图的作用，在量子场论。这种回路理论给出了解释磁光混合系统实验观测的统一图象，并且非常容易应用于任何复杂问题而无需任何计算。
英文摘要：
The input-output formalism is the basis to study the response of an optical cavity to the external stimulations. The existing theories usually handle cavity systems with only one internal mode. However, there is growing interest in more complex systems, especially the hybrid cavity-matter systems, which contains at least two internal modes, one or more from the optical cavity and the matter, respectively. Here we propose a graphical loop theory to calculate and visualize the reflection and transmission spectrum of such multi-mode cavity, resembling the role of Feynman diagrams in the quantum field theory. This loop theory gives a unified picture to interpret the experimental observations on a hybrid magnet-light system, and is extremely easy to apply to arbitrary complicated problems without any calculations.
