摘要
电注入半导体激光器相较于其他类型激光器具有电光转换效率高、体积小、寿命长等优势,近年来在显示、材料加工、医疗、通讯等领域的市场占有份额日益增长.激光器的模式特性直接影响激光器的输出性能,如功率、光束质量、光谱线宽等通过引入人工微结构,结合宇称时间对称、连续谱束缚态以及多模腔杂化调控手段,不仅可以拓展半导体激光器的物理研究范畴,同时有效优化激光器的性能,进一步增加了半导体激光器的多元应用场景.本文从模式调控的角度出发,对电注入下的人工微结构半导体激光器展开综述,包括国内外研究发展现状、物理原理以及相应的应用,最后进行了总结与展望.
Electrically injected semiconductor lasers have several advantages over other lasers, such as high electro-optical conversion efficiency, small size, and long lifetime. Recently, the demand for semiconductor lasers has grown in several areas, including displays, material processing, medicine, communication, and other fields.Mode characteristics in lasers can directly modulate their performance, including the output power, beam quality,and spectrum linewidth. The performance of semiconductor lasers can be optimized by introducing artificial microstructures combined with mode control methods, including parity-time symmetry, bound states in the continuum, and compound cavity, which can expand relevant physical research and their commercial applications.In this paper, first, the objective of mode control is introduced. Then, the developments in electrically injected semiconductor lasers, including domestic and international research studies, physical principles, and corresponding applications, are reviewed. Finally, conclusions and future outlooks are discussed.
