摘要:

研究了光子晶体腔和非共振量子点在腔或量子点共振激发下的耦合。测量量子点和腔的线宽作为激发激光功率的函数。我们表明,通过观察腔发射测量的量子点的线宽,是显着加宽的理论估计相比。这表明在量子点和腔之间存在额外的非相干耦合。

英文摘要:

We study the coupling between a photonic crystal cavity and an off-resonant quantum dot under resonant excitation of the cavity or the quantum dot. Linewidths of the quantum dot and the cavity as a function of the excitation laser power are measured. We show that the linewidth of the quantum dot, measured by observing the cavity emission, is significantly broadened compared to the theoretical estimate. This indicates additional incoherent coupling between the quantum dot and the cavity.
