An Advanced Dynamic Model for Semiconductor Optical Amplifiers and Laser Diodes

We propose a unified time-domain dynamic model for both semiconductor optical amplifiers and laser diodes by employing a set of multi-longitudinal-mode coupled wave rate equations. A novel split-step method has been developed for the numerical solution of the equation set. To demonstrate the capabilities of the model, some calculation results for conventional and distribute feedback-type gain-clamped semiconductor optical amplifiers are presented.
