摘要

固体中量子辐射的光发射体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率,许多固态系统从主体材料中提取光子的效率很低。在本文中,我们实验研究了在平面金刚石表面下约8nm和平面银镜附近植入氮空位缺陷系综的发射光谱。扫描钻石和镜面之间的距离,我们观察到光谱发射功率提高了3倍。我们建立了一个基于经典偶极子的模型,并解释了这些观测结果是由发射器远场干扰引起的。

Nitrogen-vacancy defect emission spectra in the vicinity of an adjustable silver mirror
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.
