Perfect Absorption and Reflection Modulation Based on Asymmetric Slot-Assisted Gratings without Mirrors
As a perfect graphene absorber without any external mirrors, we proposed asymmetric slot-assisted grating structures supporting two degenerate resonant modes of the guided-mode resonances (GMR) and the quasi-bound states in the continuum (quasi-BIC). The GMR mode functions as an internal mirror in c...
