We demonstrate both experimentally and numerically multifold enhancement of magneto-optical effects in subwavelength dielectric nanostructures with a magnetic surrounding exhibiting localized magnetic Mie resonances. We employ amorphous silicon nanodisks covered with a thin nickel film and achieve the 5-fold enhancement of the magneto-optical response of the hybrid magnetophotonic array of nanodisks in comparison with a thin nickel film deposited on a flat silica substrate. Our findings allow for a new basis for active and nonreciprocal photonic nanostructures and metadevices, which could be tuned by an external magnetic field.

纳米天线中的米氏共振增强了磁光响应。

我们展示了在实验和数值上亚光介电纳米结构中磁光学效应的多重增强,其中磁周围表现出局部磁Mie共振。我们采用覆盖有薄镍膜的非晶硅纳米盘,与沉积在平坦二氧化硅基板上的薄镍膜相比,实现了纳米盘混合磁光子阵列的磁光响应提高了5倍。我们的发现为有源和不可逆的光子纳米结构和元设备提供了新的基础,可以通过外部磁场对其进行调整。
