A quasi three-dimensional dynamic model is developed to investigate the multimode operation of index guided vertical cavity surface emitting lasers. Detailed index profiles of lasers such as dielectric quarter-wave Bragg reflectors are considered for the compuation of optical field distribution. In addition, current spreading, carrier diffusion and spatial hole burning are taken into consideration. Optical fields, carrier concentration and resonant frequency of the transverse modes are calculated in a self-consistent manner by the time domain algorithm and beam propagation method. Using this model, the stability of single mode operation of vertical cavity surface emitting lasers is analysed.read more
