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

超润滑增强的高灵敏度紫外石墨烯-超材料集成电光调制器

研究了具有超润滑性的基于石墨烯-等离子体超材料纳米机械系统（NEMS）的紫外（UV）电光调制系统。由于石墨烯在紫外区具有很强的光吸收强度，结合基于表面等离激元的超材料结构，UV NEMS电光调制器的调制深度是可见光区对应调制器的8.5倍。 . 同时，由于其极低的摩擦系数，超润滑性显着降低了紫外电光调制系统的功耗。它还显着提高了调制器的响应速度，响应时间降至纳秒级。调制电压可以等于或小于 150 mV。
