The increased use of optics in information processing and transmission systems motivates the development of self-consistent opto-electronic transient simulators. This letter presents a technique to significantly improve the DC and transient convergence behavior of a modified nodal analysis based optoelectronic simulation framework by allowing optical device models to be switched between a linear formulation using real and imaginary fields to a non-linear magnitude and phase representation. Configurable multilayer filters and optical ring modulators are used as examples to demonstrate the effectiveness of this approach in obtaining robust simulation convergence.
