主动控制光的能力一直是一个主要的科学和技术目标。我们提出了一个方案，允许利用非互易磁等离子体效应的光的主动控制。作为概念的证明，我们施加电流信号通过磁等离子体多层膜中的金属薄膜，发现动态光子非互易性出现在磁光材料层中，由于从电流信号感应的磁场，并调制捕获在金属表面的表面等离子体极化激元和反射的光。该概念为光的主动控制提供了一种可能的途径，并可能在等离子体纳米电路技术的超快光电信号处理和无线激光通信技术的超快/大孔径自由空间电光调制平台等方面找到潜在的应用。
The ability to actively control light has long been a major scientific and technological goal. We proposed a scheme that allows for active control of light by utilizing the nonreciprocal magnetoplasmonic effect. As a proof of concept, we applied current signal through an ultrathin metallic film in a magneto-plasmonic multilayer and found that dynamic photonic nonreciprocity appears in magnetic-optical material layer due to the magnetic field being induced from current signal and modulates surface plasmon polaritons trapped in the metal surface and the light reflected. The proposed concept provides a possible way for the active control of light and could find potential applications such as ultrafast optoelectronic signal processing for plasmonic nanocircuit technology and ultrafast/large-aperture free-space electro-optic modulation platform for wireless laser communication technology.
