摘要

我们研究了多层石墨烯介电超材料的太赫兹红外电磁特性，并提出了新的基于波导的器件:具有高调制深度(>在0.07 eV石墨烯的费米能量变化时38 dB)或极端灵敏度(>在0.001 eV费米能量变化时调制深度13.2 dB)的调制器，以及可调谐的通带滤波器(每0.004 eV费米能量变化10%的中心频移)。

Ultrasensitive terahertz waveguide modulators using graphene metamaterials

We study terahertz-infrared electromagnetic properties of multilayer graphene-dielectric metamaterial and present novel waveguide-based devices: modulators with high modulation depth (> 38 dB at 0.07 eV graphene's Fermi energy change) or extreme sensitivity (modulation depth of > 13.2 dB at 0.001 eV Fermi energy variation), and tunable passband filters (10% central frequency shift per 0.004 eV Fermi energy change).
