Enhanced Optical Transmission through a Hybrid Bull’s Eye Structure Integrated with a Silicon Hemisphere

Enhanced Optical Transmission through a Hybrid Bull’s Eye Structure Integrated with a Silicon Hemisphere

In this work, we demonstrate a novel structure that can generate extraordinary optical transmission with a silicon hemisphere placed on a conventional bull’s eye structure. There is a single subwavelength aperture surrounded by concentric periodic grooves on a substrate. The extraordinary optical tr...
