Using the coupled-mode theory, we study the transmission of surface plasmon polaritons (SPPs) guided by a thin metal film through an array of N identical nanowires, which are parallel to each other and to the surface of the metal film. By varying the parameters of the nanowire array, one can control the intensity of the transmitted SPP. Furthermore, we propose a novel mechano-optical modulation technique. The intensity of the transmitted SPP is modulated by changing the distance between the nanowire array and the metal film. The modulation frequency is in the kilohertz or megahertz range, owing to the unique mechanical properties of nanowires.
利用耦合模理论，我们研究了由薄金属膜引导的表面等离激元极化激元（SPP）通过N个相同纳米线阵列的传输情况，这些纳米线相互平行且与金属膜表面平行。通过改变纳米线阵列的参数，可以控制传输的SPP的强度。此外，我们提出了一种新颖的机械光调制技术。通过改变纳米线阵列与金属膜之间的距离来调制传输的SPP的强度。由于纳米线独特的机械性能，调制频率在千赫兹或兆赫兹范围内。
