Deterministic nanoassembly of a coupled quantum emitter–photonic crystal cavity system
T Van der Sar, J Hagemeier, W Pfaff, EC Heeres… - Applied Physics …, 2011 - pubs.aip.org
Controlling the interaction of a single quantum emitter with its environment is a key
challenge in quantum optics. Here, we demonstrate deterministic coupling of single nitrogen-
vacancy (NV) centers to high-quality photonic crystal cavities. We preselect single NV
centers and position their 50-nm-sized host nanocrystals into the mode maximum of
photonic crystal S1 cavities with few-nanometer accuracy. The coupling results in a strong
enhancement of NV center emission at the cavity wavelength.
