Abstract :
We experimentally report on dynamics of two mutually coupled vertical-cavity surface-emitting lasers (VCSEL) operating in the parallel injection scheme, that is the polarizations of the free-running VCSEL1 and VCSEL2 are parallel to each other. The VCSELs are biased such that their free-running output powers are matched and they operate around 852 nm. Both VCSELs undergo a Hopf bifurcation with excitation of limit-cycle time-periodic dynamics at the relaxation oscillation frequency. The evolution of nonlinear dynamics and synchronization mechanisms is investigated.
