Tunable ultra-high quality factor graphene absorber based on semicylindrical silica array and distributed Bragg reflector structure
We propose a tunable narrowband absorber by utilizing a graphene monolayer placed between a dielectric semicylindrical array and a multilayer silica/silicon distributed Bragg reflector (DBR) structure. The multi-band perfect absorption can be achieved due to the excitation of multiple resonant modes...
