DOI: 10.1016/j.carbon.2020.05.046

Abstract: Abstract In this work, we report an intensive theoretical study on the achieving of multiple ultra-sharp and near-unity absorption in a cavity enabled graphene absorber. The plasmonic-induced magnetic resonance, i.e., magnetic plasmon is excited and… read more here.

DOI: 10.1016/j.optcom.2019.124559

Abstract: Abstract We propose a low-loss broadband modulator by combining plasmonic effect with graphene to realize highly efficient modulation on the SOI (Silicon-On-Insulator) platform. Due to a hybrid plasmonic waveguide including buried silicon waveguide and silver… read more here.

DOI: 10.1021/acssuschemeng.8b04338

Abstract: Graphene-like carbon nitride supported plasmonic Au NPs with physical barrier-free interface (Au/C3N4) were in situ synthesized by one-step polymerization of the homogeneous mixture of HAuCl4 and urea. The plasmonic graphene-like structure of Au/C3N4 with the… read more here.

DOI: 10.1364/ao.57.006645

Abstract: By utilizing the ultrafast dynamics of the photo-excited electrons in graphene, we theoretically present an ultrafast all-optical plasmonic modulator. With the help of an external pump, the femtosecond thermodynamics of the hot carriers can tune… read more here.
