Photocurrent Enhancement of Graphene Photodetectors by Photon Tunneling of Light into Surface Plasmons
Alireza Maleki, Benjamin P. Cumming, Min Gu +3
We demonstrate that surface plasmon resonances excited by photon tunneling through an adjacent dielectric medium enhance photocurrent detected by a graphene photodetector. The devi…

Curved Gratings as Plasmonic Lenses for Linearly Polarised Light
Alireza Maleki, Thanh Phong Vo, Antoine Hautin +3
The ability of curved gratings as sectors of concentric circular gratings to couple linearly polarized light into focused surface plasmons is investigated by theory, simulation and…
