Enhanced Reflected Group Delay with Optical Tamm State via Graphene-Dielectric Bragg Mirror Configuration

Figure 2

(a) Reflectance R, (b) reflected phase , and (c) reflected group delay as functions of frequency for different Fermi energies in the graphene-1D PC structure. For comparison, reflectance R, reflected phase , and reflected group delay without graphene is shown as well. Other parameters are the same as before.
