| Relaxation oscillation frequency and damping rate are the important characteristics of vertical cavity surface emitting laser (VCSEL). These two parameters are important in the current modulation because of the laser output power depend on them. In this paper, the effect of current modulation on the relaxation oscillation frequency and characteristics of cavity Solitons have been studied. The influence of current modulation bandwidth in semiconductor lasers is studied at Soliton regime. Because of having higher optical gain in cavity Solitons comparing with ordinary points in transverse plane of semiconductor laser, better results are expected from current modulation response of cavity Solitons. |
