Paper Abstract

A novel electro-optical coupled equivalent circuit model for DFB lasers is presented in the Advanced Design System (ADS) computer-aided design environment, according to theoretical analysis for the input impedance equivalent circuit and the single-mode rate equations of distributed feedback (DFB) lasers. This model considers the influences of the input impedance and parasitic parameters of DFB laser modules, and which can emulate its voltage-current-light (V-I-L) static and dynamic response process. The simulation results show a good agreement with the measured results quoted from a literature on the direct current (DC) bias characteristics and small-signal frequency response characteristics. Therefore, the model provides great reference values in utilizing as numerical simulation and physical design for the DFB lasers as well as optoelectronic devices with its simple form, good numerical convergence and accurate calculation.
