Abstract

The influence of cavity detuning on the nonlinear dynamics of quantum-well heterostructure lasers with harmonic modulation of the pump current is analyzed. Four different models of the active medium which allow us to simulate different practical situations with respect to the modulation frequency and cavity detuning are used. As shown, different nonlinear regimes, including period doubling, chaos, and generalized bistability, can be obtained either with the cavity detuning from the maximum gain band or near the laser threshold. Effects of the radiation polarization on the laser performance are studied too. Parameters of the current modulation and spectral detuning of laser diodes are considered in relation to optical communication and optoelectronic applications.
