Figures & Tables

Fig. 1. Schematic diagram of the graphene–1D-PC composite structure. Incident light is assumed to be TM-polarized. Surface of the graphene layer is defined as the plane of z=0. Here, the period for the PC is T=20.

Fig. 2. (a) Reflectance of the graphene–1D-PC configuration (solid line), reflection coefficient rGra for a graphene top-layer interface (dash dot line), and reflection coefficient rDBR for a top-layer PC interface (dash line) as functions of wavelength. For comparison, the reflectance of the configuration without the graphene layer is also shown (short dash line). (b) The phases of rGra (dash dot line), rDBR (short dash line), and rDBRrGrae2iϕ (solid line) as functions of wavelength. (c) The reflectance as a function of wavelength for different Fermi energies in the graphene–1D-PC composite configuration.
