Abstract: | The dynamics of a negative gain suppression factor laser diode subjectedto injection current modulation is similar to that of a damped nonlinearoscillator under periodic forcing. Quasi-periodicity, frequency lockingand chaos may be present, depending on the values of the forcingparameters. We have found, for some parameter values, type-Iintermittent behavior and crisis-induced intermittency. Scaling lawswere obtained for the duration of the laminar phase and the chaos-chaosswitchings, respectively. The scale exponents are very close to thoseexpected for one-dimensional unimodal maps. |
