Paper Abstract

A digital-controllable broadband analog optical chaos source is proposed. An analog-digital hybrid electro-optic feedback loop is introduced to enhance the robustness of the semiconductor laser based chaos system. The scheme could generate a broadband optical chaotic signal of high dynamical complexity. Robust digital synchronization strategies can be used for the proposed optical chaos sources. Compared with the existing schemes, the adoption of a semiconductor laser with self-feedback reduces the requirement on the processing speed of digital components. Meanwhile, the hybrid system structure could be simplified markedly. The proposed chaotic source has potential in long-haul secure fiber communication, chaotic radar, random number generation, and so on..
