我们提出了可见光波长电控等离子体谐振器的实验演示。这是通过使用放置在金属薄膜上的悬浮等离子体纳米线（NW）来实现的。通过将纳米机电结合到等离子体纳米线中，我们可以机电地调整纳米线和金属膜之间的间隙。这种机电调谐极大地改变了纳米线的光学谐振特性，从而实现了等离子共振的动态调制。所提出的方法为实现在可见波长下工作的等离子体构件的电控制提供了一条有前途的途径。
We present an experimental demonstration of electrically controlled plasmonic resonators in visible wavelengths. This is accomplished by employing a suspended plasmonic nanowire (NW) placed on a metallic film. By incorporating nanoelectromechanics into the plasmonic NW, we electromechanically tune the gap between the NW and the metallic film. This electromechanical tuning dramatically changes the optical resonant properties of the NW, enabling dynamic modulation of the plasmon resonances. The proposed approach provides a promising route for achieving electrical control of plasmonic building blocks operating at visible wavelengths.
