混沌激光具有宽频谱、类噪声、低相干等特性,在通信、雷达、传感等领域有广泛的应用。本文介绍了混沌半导体激光器的3种主要工作机制,分别为光反馈、光注入和光电反馈;重点研究典型混沌半导体激光器的频谱带宽、时延特征,以及复杂度等性能及其研究进展;进一步论述光子集成混沌半导体激光器的发展趋势;最后介绍混沌半导体激光器在保密光通信、随机数生成器、激光雷达、分布式光纤传感、混沌光时域反射计等领域的应用现状。本文可为高带宽、低时延混沌半导体激光器的发展和应用前景提供借鉴。
Progress of Chaotic Semiconductor Lasers and Their Applications(Invited)
Chaotic laser is a kind of unstable output form of semiconductor laser,with the characteristics of broad spectrum,noise-like and low coherence,which has a wide range of applications in the fields of communication,radar and sensing.This paper introduces three main working mechanisms of chaotic semiconductor lasers:optical feedback,optical injection and optoelectronic feedback method,and focuses on the chaotic performance of typical chaotic semiconductor lasers such as spectral bandwidth,time-delay characteristics as well as complexity and their research progress;then focuses on the development trend of photonically-integrated chaotic semiconductor lasers;at last describes the role of chaotic semiconductor laser in the classified optical communication,random number generator,LiDAR,distributed fiber optic sensing technology,chaotic optical time-domain reflectometer and other fields.This review would provide a reference for the development and application prospects of chaotic semiconductor lasers with broadband power spectrum and low time delay signatures.
