Abstract
A laser model based on rate equations for the simulation of high-speed optical access networks using directly modulated lasers is presented. The laser model is implemented into a commercial microwave simulator (Microwave Design System (MDS), Hewlett Packard). The extraction of dc- and small-signal RF parameters of the laser is described. The laser model is verified by the very good agreement of simulated and measured large-signal intensity and chirp waveforms. Model validity is further confirmed by comparing measured and simulated 10Gbit/s eye diagrams after up to 100 km of standard fiber.
