Abstract

As a result of gain saturation, a ring vertical-cavity surface-emitting laser (VCSEL) has two thresholds: the lasing and the solitonic threshold. The evolution of spatial solitons in the semiconductor laser medium is modeled using the 1D wave equation, and the paraxial wave equation is presented. In the equation, k0 is the wave number, n0 is the linear refractive index, R is the anti-guiding factor and αtot, the loss. g0 is the unsaturated gain defined as g0(Np) = Γα·(Np-N0), where Γ is the confinement factor, α is the differential gain, Np is the carrier density due to the pump and N0 is the carrier density for transparency. n2, the effective nonlinear refractive index is given by n2 = R·g0/2k0Isat, where Isat is the saturation energy - Isat = hν/(Γατsp).
