Abstract
A graphene plasmonic perfect absorber (GPPA) platform with narrowband perfect absorption in the multispectral range is proposed. Artificially tunable absorption response for the GPPA can be achieved via the external stimuli by the polarization state of the illumination. Near-perfect modulation depth (MD) of â¼100% and the ultra-high relatively modulation intensity (MI) up to 3590 are achieved for the graphene plasmon switch via an electrical-control treatment. The positions of the absorption peaks can be quantitatively shifted by the Fermi energy for the GPPA.236
