We have demonstrated efficient production of triggered single photons by coupling a single semiconductor quantum dot to a three-dimensionally confined optical mode in a micropost microcavity. The efficiency of emitting single photons into a single-mode traveling wave is approximately 38%, which is nearly 2 orders of magnitude higher than for a quantum dot in bulk semiconductor material. At the same time, the probability of having more than one photon in a given pulse is reduced by a factor of 7 as compared to light with Poissonian photon statistics.
我们已经证明，通过将单个半导体量子点耦合到微柱微腔中的三维受限光学模式，可以高效地产生触发单光子。将单光子发射到单模行波中的效率约为38%，这比体半导体材料中的量子点高出近两个数量级。同时，与具有泊松光子统计的光相比，给定脉冲中出现多个光子的概率降低了7倍。
