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 8 nm 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.
