Abstract

In this paper, after taking into account two situations that the polarization of the injection light is parallel or orthogonal with the solitary vertical-cavity surface-emitting laser (VCSEL) output light, the nonlinear dynamic characteristics of an optical injection VCSEL are investigated numerically. The simulated results show that VCSEL can exhibit periodic oscillations, deterministic chaos and other complex instabilities under optical injection. For parallel or orthogonal optical injection, the same injection coefficients have different effects on the output of VCSEL. By properly adjusting the injection strength or detuning frequency, the dynamical state of the laser output can be controlled to a fixed state, and the polarization of the VCSEL output light can also be controlled.
