论文摘要
用于操纵单量子发射器的发光特性的纳米光子系统的开发对于量子通信和计算至关重要。介电纳米系统可以通过固有的电气和磁共振为光控制的各种机会，但是尚未发现它们的全部潜力。在这里，研究了位于硅纳米孔子近场区域的纳米原子座中NV中心的发射特性。在实验上证明，可以通过与球形纳米ant虫的耦合来修改单个NV中心的自发发射速率，从而将寿命分布的模式从16 ns降低至9 ns。还表明，与裸尼诺德蒙德的强度相比，与圆柱纳米丹尼亚偶联的150 nm纳米座中的多个NV中心收集的光致发光发射强度增加了50％以上。
The development of nanophotonics systems for the manipulation of the 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, the emission properties of 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 approximately 2 times from 16 ns to 9 ns. It is also shown that the collected intensity of photoluminescence emission from the multiple NV centers in 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
