我们证明了一维光子晶体纳米束腔与单个量子点之间的强耦合。由于纳米束腔的高品质因数（类似于25000）和小模体积[0.38 X（n/lambda）（3）]，观察到具有226 μ eV真空拉比分裂的反交叉行为。量子点-腔耦合强度与腔衰减率的比率，这是量子光学应用的品质因数，估计为2.1。这是迄今为止报道的基于量子点的腔量子电动力学系统中的最高值。(C)2011年美国物理学会。[doi：10.1063/1.3579535]
We demonstrated the strong coupling between a one-dimensional photonic crystal nanobeam cavity and a single quantum dot (QD). Thanks to a high quality factor (similar to 25 000) with small mode volume [0.38 X (n/lambda)(3)] of the nanobeam cavity, an anticrossing behavior with a vacuum Rabi splitting of 226 mu eV was observed. The ratio of the QD-cavity coupling strength to the cavity decay rate, which is a figure of merit of quantum optical applications, is estimated to 2.1. This is the highest value among any QD-based cavity quantum electrodynamics systems reported so far. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3579535]
