Abstract

Silicon-vacancy (SiV) centers in diamond are bright sources of indistinguishable single photons. We report fabrication of nanowires coupled to single SiV by deterministic ion implantation, yielding greatly enhanced light coupling compared to SiV in bulk.

Enhanced Quantum Nano-Sources Based on Silicon-Vacancy Centers in Epitaxially Grown Diamond Nano-Pyramids

The negatively charged silicon-vacancy center (SiV) in diamond is a potential high-quality source of single-indistinguishable photons for quantum information processing and quantum electrodynamics applications[1]. Protected by inversion symmetry, the SiV possesses bright narrow-band and spectrally stable optical transition. However, when embedded in bulk diamond, this emitter suffers from relatively low extraction efficiency attributed to total internal reflection as well as nondeterministic location. On the other hand, its implementation in nanodiamonds or nanostructures prepared by a top-down approach can mitigate the issue of total internal reflection, but impeded by optical dephasing owing to their degraded surface quality.

Cavity-Enhanced Single-Photon Source Based on the Silicon-Vacancy Center in Diamond

Sources of individual photons have applications in quantum cryptography, computation, and metrology, but truly scalable sources are still needed. The authors couple silicon-vacancy centers to a high-$Q$ microcavity, yielding a room-temperature source with the potential for high efficiency, brightness, and spectral purity. This setup improves spectral density by more than two orders of magnitude and could offer single-photon rates above 1 GHz, as well as generation of indistinguishable photons.

A Bright Single Photon Source Based on a Diamond Nanowire

Thomas M. Babinec, Birgit Hausmann, Muhammad Jibran Khan +4 more

The development of a robust light source that emits one photon at a time is an outstanding challenge in quantum science and technology. Here, at the transition from many to single photon optical communication systems, fully quantum mechanical effects may be utilized to achieve new capabilities, most notably perfectly secure communication via quantum cryptography. Practical implementations place stringent requirements on the device properties, including stable photon generation, room temperature operation, and efficient extraction of many photons. Single photon light emitting devices based on fluorescent dye molecules, quantum dots, and carbon nanotube material systems have all been explored, but none have simultaneously demonstrated all criteria. Here, we describe the design, fabrication, and characterization of a bright source of single photons consisting of an individual Nitrogen-vacancy color center (NV center) in a diamond nanowire operating in ambient conditions. The nanowire plays a positive role in increasing the number of single photons collected from the NV center by an order of magnitude over devices based on bulk diamond crystals, and allows operation at an order of magnitude lower power levels. This result enables a new class of nanostructured diamond devices for room temperature photonic and quantum information processing applications, and will also impact fields as diverse as biological and chemical sensing, opto-mechanics, and scanning-probe microscopy.
