Abstract

We report on the possibility of synchronizing two free-running quantum dot spin-polarized vertical-cavity surface-emitting lasers (QD spin-VCSELs) in a master-slave configuration. Their dynamics are studied by simulating the modified spin-flip model, and various dynamical regions are evaluated with the help of a one-parameter bifurcation technique. We show that, under proper injection conditions, the two QD spin-VCSELs can achieve high-quality chaos synchronization. The current study paves the way for the applications of QD spin-VCSELs to chaos-based communication and secure key distribution.
