论文摘要
固态中量子辐射的光学发射器是利用量子力学定律的新兴技术的重要组成部分。由于其相对较高的折射指数，从宿主材料中提取光子的效率很低。在本文中，我们通过实验研究了氮散布缺陷的发射光谱，该集合在平面钻石表面以下和平面银镜附近植入的氮缺陷。在扫描钻石与镜子之间的距离时，我们观察到了频谱发射功率的增强，最高为3倍。我们基于经典的偶极子构建了一个模型，并阐明了观测值是由于发射器远场的干扰引起的。
Optical emitters of quantum radiation in the solid state are important building blocks for emerging technologies making use of the laws of quantum mechanics. The efficiency of photon extraction from the host material is low for many solid-state systems due to their relatively high index of refraction. In this article we experimentally study the emission spectrum of an ensemble of nitrogen-vacancy defects implanted around 8nm below the planar diamond surface and in the vicinity of a planar silver mirror. Scanning the distance between diamond and the mirror, we observe an enhancement of the spectral emission power by up to a factor of 3. We construct a model based on classical dipoles and elucidate the observations as being caused by interference in the far field of the emitters.
