摘要: Optical chaos generated by chaotic lasers has been widely used in several important applications, such as chaos-based communications and high-speed random-number generators. However, these applications are susceptible to degradation the presence of time-delay (TD) signature identified from output. Here we propose achieve concealment TD signature, along with enhancement bandwidth, three-cascaded vertical-cavity surface-emitting (VCSELs). The cascaded system is composed an external-cavity master VCSEL, a solitary intermediate slave VCSEL. Through mapping evolutions bandwidth parameter space injection strength frequency detuning, photonic generation polarization-resolved wideband numerically demonstrated for wide regions parameters.
