摘要:

石墨烯独特的光学和电子性质使人们能够实现有源光学器件。虽然已经证明了几种类型的基于石墨烯的光子调制器,但将石墨烯的多功能性与等离子体/金属结构的亚波长场限制相结合的潜力尚未完全实现。在这里,我们报告的混合石墨烯等离子体调制器的制造和研究。我们考虑了几种类型的调制器,并确定了最有前途的光调制在电信和近红外。我们的概念验证结果为在芯片上实现用于光通信的高效石墨烯基有源等离子体波导器件铺平了道路。

英文摘要:

The unique optical and electronic properties of graphene allow one to realize active optical devices. While several types of graphene-based photonic modulators have already been demonstrated, the potential of combining the versatility of graphene with subwavelength field confinement of plasmonic/metallic structures is not fully realized. Here we report fabrication and study of hybrid graphene-plasmonic modulators. We consider several types of modulators and identify the most promising one for light modulation at telecom and near-infrared. Our proof-of-concept results pave the way towards on-chip realization of efficient graphene-based active plasmonic waveguide devices for optical communications.
