Applications of PSPICE simulation software to the study of optoelectronic integrated circuits and devices

Software models for Si and GaAs pin photodetectors are described, for use in the simulation of optoelectronic integrated circuits (OEICs). These preliminary models, which include the effects of dark current and lumped internal impedance, are completely integrable with PSPICE software, and may be used to study the operating characteristics of independent devices and cascaded components in complex OEICs. Parametric device dependence on applied bias, doping density, and wavelength of incident light are also established. The simulation of more advanced OEICs can be implemented with the subsequent modeling of other passive and active components, including waveguide modulators and light emitting sources. The use of PSPICE simulation software in the study of optoelectronic devices and circuits described should find wide application in upper division core or elective optical electronic courses and laboratories
