Light polarization rotators and nonreciprocal optical isolators are essential building blocks in photonics technology. These macroscopic passive devices are commonly based on magneto-optical Faraday and Kerr polarization rotation. Magnetoplasmonics, the combination of magnetism and plasmonics, is a promising route to bring these devices to the nanoscale. We introduce design rules for highly tunable active magnetoplasmonic elements in which we can tailor the amplitude and sign of the Kerr response over a broad spectral range.
光偏振旋转器和非互易光隔离器是光子学技术中的基本构建块。这些宏观无源器件通常基于磁光法拉第和克尔偏振旋转。磁等离子体学是将这些器件应用于纳米尺度的一种很有前途的方法，它结合了磁性和等离子体学。我们引入了高度可调谐的主动磁等离子体元件的设计规则，通过这些规则可以在很宽的光谱范围内调整克尔响应的幅度和符号。
