我们提出了一种辅助在频率和时间域中对光学电路进行建模的工具。该工具基于节点的定义，该节点既可以具有瞬时输入-输出关系，也可以具有不同的状态变量(例如，温度和载流子密度)以及这些状态的微分方程。此外，每个节点都可以访问其输入历史的一部分，从而允许创建延迟线或数字滤波器。此外，节点可以包含子节点，从而允许创建分层网络。该工具可用于多种应用，如光纤环形滤光片的频域分析、光放大、微盘和微腔的时域分析。虽然我们主要使用这个工具来建模光学电路，但它也可以用于其他类型的动态系统的建模，例如电路和神经网络。(C)2012年美国光学学会
We present a tool that aids in the modeling of optical circuits, both in the frequency and in the time domain. The tool is based on the definition of a node, which can have both an instantaneous input-output relation and different state variables (e.g., temperature and carrier density) and differential equations for these states. Furthermore, each node has access to part of its input history, allowing the creation of delay lines or digital filters. Additionally, a node can contain subnodes, allowing the creation of hierarchical networks. This tool can be used in numerous applications such as frequency-domain analysis of optical ring filters, time-domain analysis of optical amplifiers, microdisks, and microcavities. Although we mainly use this tool to model optical circuits, it can also be used to model other classes of dynamical systems, such as electrical circuits and neural networks.
