We demonstrate the breaking of axial symmetry of the transverse field distribution in such a device. In particular, we show that if the linewidth enhancement factor is sufficiently large dynamical regimes with broken axial symmetry can exist up to very high diffusion coefficients 10 um^2/ns.application/pdfeng510Vertical cavity surface emitting laserLaser dynamicsCarrier diffusionReport
