Using developed theoretical model of mode synchronization in semiconductor
passively mode locked laser (PMLL) we have calculated influence of length and relaxation rate
of saturable absorber (SA) on operation regimes of PMLL. We included in consideration the
influence of emission rate of free carriers from the levels of dimensional quantization in the SA
and found out the optimum operating voltage for PMLL in the fundamental synchronization
mode (one harmonic component) as -1.5 - -2 V with optimal length of the SA as 0.637 mm.
Keywords: : InGaAlAs/InGaAs/InP heterostructures; passively mode locked laser; operation regimes; absorber characteristics.
