Simulations based on a carrier heating model are performed to investigate the behavior of a directly modulated 1.55-/spl mu/m InGaAsP distributed feedback (DFB) laser diode (LD). Results show that bandgap shrinkage has a significant effect on the sim

A detailed numerical analysis of the nonlinear dynamics of a directly modulated 1.55 μm InGaAsP distributed-feedback laser diode (LD) is carried out. Results show that when simulating the nonlinear dynamics of LDs, it is important to account for the

The calculated gain spectrum of a semiconductor laser based on a generic modal gain model reveals a gain peak that is higher than measured. Analyses of the model and the gain mechanism in semiconductor lasers suggest that the accuracy of the model ca

The stability of homogeneously pumped single‐section laser diodes is analyzed theoretically and it is found that under certain bias conditions negative gain suppression factor laser diodes (NGSFLDs) self‐pulsate. An analytical condition for self

A numerical analysis is carried out to investigate the influence of injecting either unmodulated or modulated light from an external laser diode (LD) into a 1.55 micrometers InGaAsP distributed feedback (DFB) self-pulsating (SP) LD. Injection of weak
