Abstract
This paper presents a methodology for the incorporation of actively configurable interference-based optical elements into a circuit-level optoelectronic simulator. The self-consistent optoelectronic simulator is based on modified nodal analysis. The paper uses ring-resonator-based devices as examples of configurable devices. Construction of compact models of these devices from optical scattering and the waveguide elements using fundamental principles is presented in detail. In the results section, accuracy of the compact model of the ring resonator is first confirmed for static devices for steady-state and transient conditions. Last, the devices are placed in a complex optical circuit and used to modulate an optical carrier and select a particular channel from a multichannel optical signal. The modelling framework proposed proved to be robust and efficient for transient simulation of configurable elements in a self-consistent optoelectronic simulation engine.
