Abstract :
The effects of nonlinear gain on the dynamics of a semiconductor laser in which the active region consists of a strained-layer structure are presented. Gain suppression is enhanced in the presence of strain, thus reducing the relaxation oscillation frequency in strained-layer lasers at very high optical powers compared with equivalent unstrained structures.
