Graphene Plasmonic Terahertz Filters and Polarizers
ORAL
Abstract
Graphene has remarkably strong interaction with light, especially in the terahertz frequency range. Free carriers in graphene exhibit Drude behavior and the Drude weight can be tuned by electrostatic or chemical doping. Graphene can support surface plasmons. In this paper, we'll show that with multiple stacked CVD graphene layers, terahertz filters and polarizers can be realized by patterning them into micro-disks and ribbons. The influence of dipole-dipole interaction on the extinction spectra will be discussed.
