Integrated chaotic lasers play a crucial role in high-speed chaotic secure communication, key generation, and distribution. However, the existing chaotic bandwidth of integrated chaotic lasers fails to meet the requirements of high-speed applications. Therefore, this study focuses on the development of integrated broadband chaotic semiconductor lasers. Based on a short-cavity distributed feedback semiconductor laser chip developed by the team in the early stage, the conditions for achieving strong light feedback in the integrated spatial light feedback structure are analyzed and the feedback cavity length is optimized. As a result, a short-cavity distributed feedback semiconductor laser with fiber/spatial dual output light is prepared. Subsequently, this laser is integrated with a reflector and adjustment device, resulting in the development of a compact 16 cm×8 cm×7 cm integrated broadband chaotic semiconductor laser with a chaotic bandwidth exceeding 30 GHz.
