Abstract
An external-cavity semiconductor laser with nonlinear optical
feedback to generate broadband chaos with time delay signature (TDS)
suppression is investigated. The system is composed of three semiconductor
lasers, one of which is regarded as the chaos generator, while the other
two play a role of a built-in nonlinear modulator in the external cavity
of the generator. The results show that by properly setting the feedback
strength and time delay of the first semiconductor laser in the nonlinear
modulator, the TDS embedded in the intensity and phase time-series of the
chaos can be effectively concealed in a wide range of frequency
detuning.
