Tunable Multiple-Step Plasmonic Bragg Reflectors with Graphene-Based Modulated Grating

We propose a novel plasmonic Bragg reflector (PBR) based on graphene with multiple-step silicon structure. The monolayer graphene bears locally variable optical properties by modulation of electric fields, and the periodical change of effective refractive index on graphene can be obtained by externa...
