Abstract

We present the continuous frequency modulation of a metamaterial resonance using selective damping of coupled plasmonic resonators with electrostatically gated graphene. A resonance frequency tuning range >150 GHz is achieved at 1.5 THz making this device suitable for use as an optoelectronic, tunable frequency modulator for THz frequencies.
