Simulation of nonlinear optical resonator circuits

Abstract

Recently, we proposed a node-based framework to model large circuits of nonlinear photonic components. This flexible tool can be used to simulate circuits that contain a variety of components both in time-domain and in frequency-domain. In this paper, we extend the node-definition of this framework such that that the linear coupling between access waveguides and resonance states in optical resonators can be more efficiently incorporated. We demonstrate that this results in an important decrease of the simulation time in large circuits of nonlinear photonic cavities.
