Abstract
Complex-valued time-resolved transmission characteristics of a semiconductor optical amplifier are measured using a spectrogram technique. A relatively simple traveling-wave density matrix model is implemented that accurately captures the evolution of complex index due to stimulated emission and carrier heating. The model shows good agreement with experimental spectrogram data.
