Riassunto:  The existence of high chaotic spiking in the dynamics of semiconductor lasers with an AC-coupled optical feedback is investigated experimentally. After chaos signal generation, the effect of attenuation feedback strength as a control parameter is studied, and the time evolution of photon density is analyzed. The chaotic instability is tested; our results exhibit monostability in dynamics. By applying different frequencies to observe the hidden regions, the chaotic dynamic results are indicated as a good candidate to hide information for satisfying the resonance phenomenon, to evaluate secure optical communication.
