摘要:
A novel method to simulate semiconductor lasers is presented that captures accurately the real and imaginary parts Of the active medium response in a broad frequency range. It is a time-domain approach based on a spatial digital filter in the role of the optical field propagator. Careful treatment of numerical dispersion makes it possible to utilize effectively most of the available numerical bandwidth and obtain a realistic description of the laser dynamics.
