We show that supersymmetry can provide a versatile platform in synthesizing a new class of optical structures with desired properties and functionalities. By exploiting the intimate relationship between superpatners, one can systematically construct index potentials capable of exhibiting the same scattering and guided wave characteristics. In particular, in the Helmholtz regime, we demonstrate that one-dimensional supersymmetric pairs display identical reflectivities and transmittivities for any angle of incidence. Optical supersymmetry is then extended to two-dimensional systems where a link between specific azimuthal mode subsets is established. Finally, we explore supersymmetric photonic lattices where discreteness can be utilized to design lossless integrated mode filtering arrangements.
我们表明,超对称性可为合成具有所需特性和功能的新型光学结构提供一个通用平台。通过利用超伴子之间的紧密关系,可以系统地构建能够展现相同散射和导波特性的折射率势。特别是在亥姆霍兹 regime 中,我们证明一维超对称对对于任何入射角都具有相同的反射率和透射率。然后,光学超对称性被扩展到二维系统,在其中建立了特定方位角模式子集之间的联系。最后,我们探索超对称光子晶格,其中离散性可用于设计无损集成模式滤波装置。
