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…
Dual-Mode Asymmetric Transmission based on Asymmetric and Orthogonal Gratings: Polarization-Dependent and -Independent Modes
Ruihan Ma, Yuqing Cheng, Mengtao Sun
A dual-mode asymmetric transmission (AT) nanodevice based on the asymmetric and orthogonal grating-film-grating (AO-GFG) structure is proposed and systematically investigated theor…
Extend the waveband of high isolation ratio and narrow band asymmetric transmission based on grating-film-grating nanostructure
Ruihan Ma, Yuqing Cheng, Mengtao Sun
A serial asymmetric transmission (AT) nanodevices based on the grating-film-grating (G-F-G) structure are proposed and studied. By showing the results of three different nanodevice…
