我们评估了限制Tamm等离子体结构的单光子提取的潜力。将单个量子点插入由沉积在分布式布拉格反射器上的金微盘组成的结构中。量子点激子线经历自发辐射的加速，而双激子线经历抑制。这种性质导致作为激发速率的函数的发射动力学和光子统计的非线性。我们表明，该设备作为一个单光子源，测量亮度为0.20 +/- 0.02收集光子每脉冲。通过对提取效率进行建模，我们表明在优化结构中可以达到60%左右的效率。(C)2012年美国物理学会。[http：//dx.doi.org/10.1063/1.4726117]
We evaluate the potential of confined Tamm plasmon structures for single photon extraction. A single quantum dot is inserted in a structure consisting of a gold microdisk deposited on a distributed Bragg reflector. The quantum dot exciton line experiences acceleration of spontaneous emission while the biexciton line experiences inhibition. This property leads to non-linearities in the emission dynamics and the photon statistics as a function of the excitation rate. We show that the device operates as a single photon source with a measured brightness of 0.20 +/- 0.02 collected photons per pulse. By modeling the extraction efficiency, we show that efficiencies around 60% can be reached in optimized structures. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4726117]
