摘要

利用两个名义上相同的器件，用外差法测量了光子晶体表面发射激光器的谱线宽度。这些基于GaAs的935 nm PCSELs在适度输出功率下获得了100-200 kHz的线宽。自然线宽被确定为$71\pm 30 \ \text{kHz}$。

Spectral Linewidth of Photonic Crystal Surface Emitting Lasers

The spectral linewidth of photonic crystal surface emitting lasers is evaluated using a heterodyne method utilizing two nominally identical devices. Linewidths of 100–200 kHz are obtained at modest output powers for these GaAs based 935 nm PCSELs. The natural linewidth is determined to be $71\pm 30 \ \text{kHz}$.
