However, the conventional continuous wave operation mode is limiting the performance and application scope of semiconductor lasers. To overcome these limitations, various controllable operation modes have been proposed and studied, such as pulsed operation, chaotic operation, and mode locking. Among them, the controllable operation mode based on the microscopic dynamics of the semiconductor laser, such as injection current modulation and optical feedback, has attracted increasing attention due to its flexibility and scalability.The UMXX00 series semiconductor lasers are widely used in practical applications due to their low cost and high reliability. However, the microscopic dynamics and controllable operation modes of UMXX00 lasers have not been fully explored. In this project, we aim to investigate the controllable operation modes of UMXX00 semiconductor lasers and reveal the microscopic mechanisms behind them.We will first conduct a literature review to summarize the current state-of-the-art techniques for controlling the operation modes of semiconductor lasers. Then, we will design and fabricate a series of UMXX00 semiconductor laser devices with different parameters, such as cavity length, doping concentration, and facet reflectivity. We will use these devices to experimentally investigate the effects of injection current modulation and optical feedback on the laser operation mode. The output characteristics of the lasers, such as output power, frequency, and optical spectra, will be measured and analyzed.Based on the experimental results, we will develop a theoretical model to describe the microscopic dynamics of UMXX00 semiconductor lasers and explain the observed operation modes. We will also investigate the scalability and practicality of the proposed controllable operation modes for different applications.Overall, this project will contribute to the understanding of the microscopic dynamics and controllable operation modes of UMXX00 semiconductor lasers, and provide valuable insights for their optimization and application.
