Cg. Lim et al., Influence of the injection current dependence of gain suppression on the nonlinear dynamics of semiconductor lasers, APPL PHYS L, 78(16), 2001, pp. 2384-2386
A detailed numerical analysis of the nonlinear dynamics of a directly modul
ated 1.55 mum InGaAsP distributed-feedback laser diode (LD) is carried out.
Results show that when simulating the nonlinear dynamics of LDs, it is imp
ortant to account for the gain suppression being dependent on the injection
current. Only when this dependency of gain suppression is included in the
conventional single-mode rate equations, can excellent agreement between si
mulated and measured results be achieved. (C) 2001 American Institute of Ph
