High sensitivity ultraviolet graphene-metamaterial integrated electro-optic modulator enhanced by superlubricity

Abstract Ultraviolet (UV) electro-optic modulation system based on graphene-plasmonic metamaterials nanomechanical (NEMS) with superlubricity is investigated. Due to the strong optical absorption intensity of graphene in UV region and combination metamaterial structure surface plasmons, depth NEMS modulator approaches as high 8.5 times compared counterpart visible light region. Meanwhile, significantly reduces power consumption due its extremely low friction coefficient. It also increases response speed modulator, time down nanoseconds. The voltage can be equal or less than 150 mV. proposed has a simple sensitivity, which supposed have important applications optoelectronic devices systems.
