Graphene-on-silicon nitride microring resonators. (a) Schematic of the graphene-on-silicon nitride microring resonator. (b)–(e) Experimental measurements of resonance spectra of the graphene-on-silicon nitride microring resonators with graphene lengths of 0 μm, 15 μm, 40 μm, and 70 μm. (f) Experimental and theoretical results of the factor as a function of graphene length. Figure 2 is reprinted from [28]. Copyright © 2015 IEEE.
