“…The first route is to assemble hybrid systems where colour centres in diamond nanocrystals or bulk diamond are coupled to the evanescent fields of cavities defined in non-diamond materials for which established nano-fabrication techniques exist: here coupling to silica micro-spheres [19,20], silica micro-disks [21], GaP micro-disks [22] and GaP micro-ring cavities [23] has been demonstrated. In a very similar fashion recent experiments have realised controlled coupling of NV − centres in nanodiamonds to GaP photonic crystal cavities [24,25,26]. In these experiments selective enhancement of the NV − ZPL could be detected in the cavity emission spectrum.…”

The development of solid-state photonic quantum technologies is of great interest for fundamental studies of light-matter interactions and quantum information science. Diamond has turned out to be an attractive material for integrated quantum information processing due to the extraordinary properties of its colour centres enabling e.g. bright single photon emission and spin quantum bits. To control emitted photons and to interconnect distant quantum bits, micro-cavities directly fabricated in the diamond material are desired. However, the production of photonic devices in high-quality diamond has been a challenge so far. Here we present a method to fabricate one-and two-dimensional photonic crystal micro-cavities in single-crystal diamond, yielding quality factors up to 700. Using a post-processing etching technique, we tune the cavity modes into resonance with the zero phonon line of an ensemble of silicon-vacancy centres and measure an intensity enhancement by a factor of 2.8. The controlled coupling to small mode volume photonic crystal cavities paves the way to larger scale photonic quantum devices based on single-crystal diamond.A number of seminal experiments have demonstrated the prospects of colour centres in diamond, in particular the negatively charged nitrogen-vacancy centre

“…In first case, the nanodiamond is brought in a close proximity to a metallic structure to achieve plasmonic coupling, 16 or positioned on top of a dielectric cavity. 17 While these techniques are suitable for nanophotonics and quantum optics, they are performed on an extremely limited number of particles at a time and are not appropriate for bio-sensing or bio-imaging. In the latter case, high energy electron beam irradiation creates ensembles of NV centers, and the important attributes of single photon emission and high contrast in the optically detected magnetic resonance (ODMR) signal are lost.…”

Enhanced photoluminescence from single nitrogen-vacancy defects in nanodiamonds coated with phenol-ionic complexes

et al. 2015

Fluorescent nanodiamonds are attracting major attention in the field of bio-sensing and biolabeling. In this work we demonstrate a robust approach to surface functionalize individual nanodiamonds with metal-phenolic networks that enhance the photoluminescence from single nitrogen vacancy (NV) centers. We show that single NV centres in the coated nanodiamonds also exhibit shorter lifetimes, opening another channel for high resolution sensing. We propose that the nanodiamond encapsulation suppresses the non-radiative decay pathways of the NV color centers. Our results provide a versatile and assessable way to enhance photoluminescence from nanodiamond defects that can be used in a variety of sensing and imaging applications.

“…Efforts to efficiently couple NVs in nanocrystalline diamond to nanophotonic structures [12][13][14][15] have been limited by poor NV optical properties in nanocrystals compared to those found in single crystal diamond. Fabricating nanophotonic devices directly from single crystal diamond has recently made important progress [11,16,17], limited primarily by fabrication difficulties related to creating thin films of single crystal diamond necessary for optical confinement in three dimensions.…”

Resonantly enhanced emission from the zero-phonon line of a diamond nitrogen-vacancy (NV) center in single crystal diamond is demonstrated experimentally using a hybrid whispering gallery mode nanocavity. A 900 nm diameter ring nanocavity formed from gallium phosphide, whose sidewalls extend into a diamond substrate, is tuned onto resonance at a low temperature with the zero-phonon line of a negatively charged NV center implanted near the diamond surface. When the nanocavity is on resonance, the zero-phonon line intensity is enhanced by approximately an order of magnitude, and the spontaneous emission lifetime of the NV is reduced by as much as 18%, corresponding to a 6.3X enhancement of emission in the zero photon line. DOI: 10.1103/PhysRevX.1.011007 Subject Areas: Nanophysics, Photonics, Quantum InformationThe diamond nitrogen-vacancy (NV) center is an optically active impurity which combines many of the desirable properties of quantum dots and laser-trapped atoms. Optical transitions of diamond NV centers can display low inhomogeneous broadening, and have been used to generate single photons [1], manipulate single electron spins [2], and control nearby nuclear spin impurities [3][4][5]. Remarkably, the room temperature electron spin coherence times of NVs can exceed a millisecond [6]. These properties make NVs a promising qubit for proposed quantum networks [7], and an attractive system for applications such as magnetometry [8] and low power optical switching [9]. An outstanding challenge limiting the use of NV centers as qubits in quantum information processing is the creation of a platform for mediating interactions between them. A promising approach to this problem is to create an onchip quantum network in which NVs interact optically via nanophotonic interconnects [10]. Coupling NVs to optical cavities plays a crucial role in this implementation by enhancing the NV emission into a well-defined optical mode, which can be efficiently coupled to waveguides and routed on-chip. Cavity enhancement of the emission is particularly important for NV centers, as it provides a means for increasing the relative brightness of the narrowband zero-phonon line (ZPL) emission relative to the broadband phonon assisted emission. The selection of the emission into the ZPL is necessary for protocols involving coherent interactions or indistinguishable photons.Demonstrating diamond-based quantum networks has recently prompted significant research into integrating NV centers with photonic devices [11]. Efforts to efficiently couple NVs in nanocrystalline diamond to nanophotonic structures [12][13][14][15] have been limited by poor NV optical properties in nanocrystals compared to those found in single crystal diamond. Fabricating nanophotonic devices directly from single crystal diamond has recently made important progress [11,16,17], limited primarily by fabrication difficulties related to creating thin films of single crystal diamond necessary for optical confinement in three dimensions.
