我们研究了基于量子阱的单节半导体二极管激光器产生的调频梳子的物理起源，隔离了梳子产生所需的基本物理。我们发现，在某些量子阱系统中确实存在梳子产生所必需的两种效应——空间烧孔（导致多模操作）和四波混频（导致锁相）。量子阱中梳状结构的产生与量子点和量子级联激光器中的梳状结构相似。讨论了这些二极管激光器的光谱相位性质和一些重要的材料参数。
We investigate the physical origin of frequency-modulated combs generated from single-section semiconductor diode lasers based on quantum wells, isolating the essential physics necessary for comb generation. We find that the two effects necessary for comb generation-spatial hole burning (leading to multimode operation) and four-wave mixing (leading to phase locking)-are indeed present in some quantum-well systems. The physics of comb generation in quantum wells is similar to that in quantum dot and quantum cascade lasers. We discuss the nature of the spectral phase and some important material parameters of these diode lasers.
