Broadband Asymmetric Transmission with Wide Spectral Tunability based on Substrate-Embedded Silicon Nanoring Arrays
Ruihan Ma, Yuqing Cheng, Mengtao Sun
In this work, we theoretically propose a broadband asymmetric transmission (AT) device based on periodic Si nanoring arrays embedded in a SiO2 substrate. Results indicate that the…

Broadband asymmetric transmission with tunable bilayer silicon nanoarrays: from visible to near-infrared
Ruihan Ma, Yuqing Cheng, Mengtao Sun
A kind of asymmetric transmission (AT) device based on bilayer silicon arrays (BSA) nanostructure is theoretically explored, which achieves high forward transmissivity and suppress…
