Progress in Chaotic Semiconductor Lasers

Chaotic laser, known for the wide-spectrum and noise-like characteristics, has been widely used in various fields such as communication, sensing and lidar. Due to the advantages of small size, stable performance and low cost, semiconductor lasers have become the main light source for the generation of chaotic laser. The traditional chaotic semiconductor lasers with optical feedback have the problems of narrow signal bandwidth, with time-delay signature, and low integration with discrete devices. For these problems, the research progress in recent years of researchers on the bandwidth enhancement, time-delay signature suppression and integrated chaotic lasers is introduced comprehensively in this paper. And the development trend and potential applications of chaotic semiconductor lasers are also prospected.
