摘要

我们提出了一种由一对耦合互补亚波长光栅组成的非对称传输(AT)器件。利用非对称介质环境和近场耦合效应，实现了在1250 nm处前向透射率高达0.96的高性能AT。

Asymmetric light transmission through bilayer complementary gratings

We propose an asymmetric transmission (AT) device consisting of a pair of coupled complementary subwavelength gratings. Asymmetric dielectric environment and near-field coupling effect are employed to realize high-performance AT with large forward transmittance of 0.96 at 1250 nm.
