Event description: 

We show that graphene can provide electro-optic properties to traditionally passive optical materials and enable efficient integrated active nanophotonic devices. We show devices with GHz absorption modulation based on ring resonators. We also report the first experimental demonstration of a graphene electro-refractive modulator with VπL of 0.14 Vcm, and minimal absorption modulation based on graphene capacitor integrated on Si3N4 with embedded high-K and high breakdown dielectric.
