We investigate the scattering properties of a single surface plasmon in metal nanowire coupled to a nitrogen-vacancy (NV) center in diamond nanocrystal under optical excitation. We demonstrate that, by spatially modulating a classical control beam, alternating regions of high reflection and absorption as well as high transmission and absorption of a single plasmon can be created in the left- and right-going directions that act as a kind of scattering grating. Such approach to induce grating gets out the well investigating region in which the weak interactions between single atoms and light is often used. The proposal may be used for chip-integrated grating, switcher and multi-channel drop filter.
我们研究了在光激发下，与金刚石纳米晶体中的氮空位（NV）中心耦合的金属纳米线中单个表面等离子体激元的散射特性。我们证明，通过对经典控制光束进行空间调制，可以在向左和向右传播的方向上创建单个等离子体激元的高反射和吸收以及高透射和吸收的交替区域，这些区域可作为一种散射光栅。这种诱导光栅的方法超出了通常研究单个原子与光之间弱相互作用的研究范围。该方案可用于芯片集成光栅、开关和多通道分路滤波器。
