Abstract

The characteristics, stability and robustness of vectorial optical vortices in a type-II optical parametric oscillators (OPO) model describing the integration of pump, signal and idler when the pump field is not resonated were experimentally studied. Mean field equations were obtained for the two orthogonal and linearly polarized amplitudes Ax and Ay of the signal and idler fields ∂tAx = -(1+iΔ)Ax+iax▽2Ax +μA*y+σ|Ay|2Ax; ∂tAy = -(1+iΔ)Ay+iay▽2Ay+μA*x +σ|Ax|2Ay; where Δ is the effective detuning, ax, ay are the diffraction coefficients, μ is proportional to the pump amplitude, and σ is the nonlinear coupling coefficient. The study focuses on the frequency degenerate case and Δ<0.
