论文摘要
观察到的干涉仪的输出是沿每个可能的光路传播的输入光束部分之间干扰的结果。在复杂的系统中，写下所有这些可能的光路并计算其累积效应可能会成为一项艰巨的任务。我们提出了一种基于直观的基于图形的方法，用于解决此问题并计算干涉测量，经典和量子的电场。我们展示了如何将加权的有向图与干涉仪相关联并定义规则以简化这些相关的图形。连续的应用规则将最终图导致，其中包含有关所需字段幅度的信息。该方法应用于腔光学和腔体增强干涉仪中的许多示例。
The observed output of an interferometer is the result of interference among the parts of the input light beam traveling along each possible optical path. In complex systems, writing down all these possible optical paths and computing their cumulative effect can become a difficult task. We present an intuitive graph-based method for solving this problem and calculating electric fields within an interferometric setup, classical and quantum. We show how to associate a weighted directed graph to an interferometer and define rules to simplify these associated graphs. Successive application of the rules results in a final graph containing information on the desired field amplitudes. The method is applied to a number of examples in cavity optomechanics and cavity-enhanced interferometers.
