Abstract

Silver gratings of hybrid structures are proposed, and their optical transmission properties are simulated by finite element method. The proposed structure is found to facilitate a broadband-enhanced transmission in the infrared region and exerts a band-stop effect in the visible region. The effects of structural parameters on transmission characteristics are also studied. Results reveal promising applications in broadband light harvesting and filtering devices.
