Graphene-Based Cylindrical Pillar Gratings for Polarization-Insensitive Optical Absorbers

Graphene-Based Cylindrical Pillar Gratings for Polarization-Insensitive Optical Absorbers

In this study, we present a two-dimensional dielectric grating which allows achieving high absorption in a monolayer graphene at visible and near-infrared frequencies. Dielectric gratings create guided-mode resonances that are exploited to effectively couple light with the graphene layer. The propos...
