Deterministic and stochastic dynamics of linear polarizations emitted by single-mode VCSELs subject to orthogonal optical injection

Abstract

We present a theoretical and experimental study of the polarization-resolved nonlinear dynamics of a 1550nm single-mode linearly polarized VCSEL when subject to orthogonal optical injection. Anticorrelated (correlated) dynamics between the two linear polarizations emitted by the VCSEL is found for negative (positive) frequency detuning. Our theoretical analysis show that deterministic dynamics with appreciable values of the standard deviation of the period of the signal can be found for negative values of the frequency detuning. We study the effect of spontaneous emission noise on the dynamics by analyzing the dependence of the average and standard deviation of the interpulse time on the injected power. We find that in general the effect of spontaneous emission noise is to increase the standard deviation of the interpulse time.
