Abstract

The optical absorption in heterostructure composed of a graphene and a doped photonic crystal is investigated theoretically. The absorption of the heterostructure is enhanced greatly due to photon localization. The absorptance can be tuned by varying either the incident angle or the thickness of graphene film. The number of absorption peaks can be tuned by varying the thickness of dielectric defect..
