Özet:

 

We studied numerically the dynamics and bifurcations route to chaos of an  optically injected semiconductor laser. The sequence of bifurcations mainly  followed the period-doubling scenario. Observations of different kinds of  injected semiconductor laser dynamical behaviors including stable state,  periodic oscillation state, quasi-periodic oscillation state, co-existence  of periodic and chaotic states, and period-3 and period-6 oscillation states  are reported.     The existence of isolated branches created from a sudden jump in the  dynamics of the semiconductor laser was also observed in the bifurcation  diagram. In order to draw a detailed picture for the dynamical behavior of  the semiconductor laser, we constructed color stability maps describing the  laser system dynamics as a function of the pumping current (P) and the  injection field strength (eta) for 2 cases, without and with gain   saturation effect.
