  • 专业解析

    半导体激光二极管(Semiconductor Laser Diode)是一种基于半导体材料的光电转换器件,通过电注入激发载流子复合产生激光。其核心结构由PN结、光学谐振腔和电极组成。当外加正向偏压时,电子与空穴在结区复合释放光子,经谐振腔多次反射形成受激发射,最终输出高方向性、单色性和相干性的激光束。

    工作原理与材料特性

    1. 能带跃迁机制

      半导体材料(如砷化镓GaAs、氮化镓GaN)的导带与价带之间存在特定能隙,载流子复合时释放能量对应特定波长光子。通过掺杂形成PN结,可实现高效率的载流子注入。

    2. 光学谐振腔

      利用晶体的解理面或外置反射镜构成法布里-珀罗腔,使光子在腔内往返放大,达到阈值条件后形成激光输出。典型腔长范围为200-500μm。
