Wide range 40-GHz passive mode-locking operation of an AlGaInAs 1.55-μm strained quantum well laser

We develop a comprehensive theoretical description of passive mode-locked semiconductor lasers based on a coarse grained time-domain approach. Under the approximation of intraband quasi equilibrium, our model accounts for the dispersion of gain, absorption and refractive index, nonlinear gain saturation from ultrafast processes, self-phase modulation, and spontaneous emission noise. We compare the predictions of our model with the performances of a quasi-40-GHz passively mode-locked AlGaInAs 1.55-μm strained quantum well laser.
