摘要
近年来,混沌激光已广泛应用于保密通信、高速随机数生成、混沌激光雷达、混沌光时域反射仪、光纤传感和测距等方面。与离散器件构成的装置不同,集成芯片具有尺寸较小、功耗较低、稳定性较好和适用于大批量生产等优点。结合混沌应用和集成芯片的优势,光子集成的混沌半导体激光器应运而生。将光子集成混沌半导体激光器分为五类,并分别介绍了国内外相关机构在集成结构、集成区域的尺寸、集成构成的特点及集成混沌激光器的应用等方面的研究进展。另外,设计并介绍了一种新型的面向蝶形封装的混沌外腔半导体激光器。
The chaos laser has received in-depth investigation in recent such as secure communications, fast physical random bit generation, years owing to its important applications, chaotic laser radar, chaotic time domain reflectometer, optical fiber sensing and ranging. The integrated chips have advantages over those setups composed of discrete components for some unique virtues such as smaller size, lower cost, better stability and reproducibility via mass production. Combining with the advantages of the chaotic applications and integrated chips, the integration of chaotic semiconductor laser arises at the historic moment. The integration of chaotic semiconductor laser is divided into five categories to introduce the domestic and oversea research progress of the relevant institutions in the respect of integrated structure, size of the integrated area, features of integration and applications of integrated chaotic laser. Finally, we design a novel butterfly packaging integrated chaotic semiconductor laser with an externalcavity.
