The transverse mode dynamics of vertical-cavity surface-emitting lasers is analyzed studying the passive cavity beam shaping mechanisms. Diffraction in the Bragg mirrors is found to favor the fundamental transverse mode compared to the higher order modes. Mode dependent effective complex reflection coefficients are computed. The effect of diffraction is compared to the effects of thermal lensing due to heating of the Bragg mirrors and of the plasma and active layer lattice.
