Abstract

An understanding of possible polarization states and transverse patterns close to a lasing threshold is provided by the Vector Complex Ginzburg Landau Equation (VCGLE) [1]. The VCGLE describes generically the amplitude of a two-component field close enough to a homogeneous Hopf bifurcation in a spatially extended system. The coupling constant, γ, between the two components of the field arises from different relaxation processes and γ = 1 represents the case in which cross-interaction is as strong as self-interaction.
