Figure 1: Ideal graphene FP cavity.

(a) Low-energy dispersion in pristine graphene. (b) Sketch of an idealized graphene FP resonator. (c) Normalized conductance through an ideal graphene cavity as a function of the dimensionless parameter kFL/π for three different finesses: F=1,600 in yellow, F=4.9 in purple and F=0.4 in blue.
