Abstract

We experimentally report on dynamics of two mutually coupled vertical-cavity surface-emitting lasers (VCSEL) operating in the parallel injection scheme, i.e., 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. The evolution of nonlinear dynamics and synchronization mechanisms is investigated when varying the coupling strength κ_inj for different detunings Δν = ν₁- ν₂ [where ν₁ and ν₂ are, respectively, the frequency of the free-running VCSEL₁ and VCSEL₂).
