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-m Strained Quantum Well laser.
