Abstract
Section titled āAbstractāThe development of nanophotonics systems for the manipulation of luminescent properties of single quantum emitters is essential for quantum communication and computing. Dielectric nanosystems enable various opportunities for light control through inherent electric and magnetic resonances; however, their full potential has not yet been discovered. Here, emission properties of nitrogen-vacancy (NV) centers in nanodiamonds placed in the near-field zone of silicon nanoresonators are investigated. It is demonstrated experimentally that the spontaneous emission rate of single NV centers in 50 nm nanodiamonds can be modified by their coupling to spherical nanoantennas, reducing the mode of the lifetime distribution by ā2 times from 16 to 9 ns. It is also shown that the collected intensity of photoluminescence emission from multiple NV centers in a 150 nm nanodiamond coupled to a cylindrical nanoantenna is increased by more than 50% compared to the intensity from the same nanodiamond on a bare substrate.
