Abstract :
The dynamic characteristics of surface emitting lasers with a saturable absorbing layer are modelled and shown to exhibit self-sustained pulsations up to 10 GHz. A set of coupled rate equations is used to investigate the regions of self-pulsations, and show that there is an optimum position for the absorbing layer within the cavity structure to produce the widest range of pulsation frequencies
