Abstract:
The dynamics of a negative gain suppression factor laser diode subjected to injection current modulation is similar to that of a damped nonlinear oscillator under periodic forcing. Quasi- periodicity, frequency locking and chaos may be present, depending on the values of the forcing parameters. We have found, for some parameter values, type-I intermittent behavior and crisis-induced intermittency. Scaling laws were obtained for the duration of the laminar phase and the chaos-chaos switchings, respectively. The scale exponents are very close to those expected for one-dimensional unimodal maps.
