The reduction of surface plasmon losses in quasi-suspended graphene
Highly confined surface plasmons on graphene attract substantial interest as potential information carriers for highly integrated photonic data processing circuits. However, plasmon losses remain the main obstacle for implementation of such devices. In near-field microscopic experiments performed at the wavelength of 10 μm we show that a substantial reduction of plasmon damping can be achieved ...
متن کاملErratum: The reduction of surface plasmon losses in quasi-suspended graphene
In the Supplementary Information file originally published with this Article, the y-axis for Supplementary Figures 1d, 1f, 5b, 5c and 5d should read 'E s (a.u.)'. These errors have been corrected in the Supplementary Information that now accompanies the Article.
متن کاملPhase-resolved surface plasmon interferometry of graphene.
The surface plasmon polaritons (SPPs) of graphene reflect the microscopic spatial variations of underlying electronic structure and dynamics. Here, we excite and image the graphene SPP response in phase and amplitude by near-field interferometry. We develop an analytic cavity model that can self-consistently describe the SPP response function for edge, grain boundary, and defect SPP reflection ...
متن کاملGraphene-based active slow surface plasmon polaritons
Finding new ways to control and slow down the group velocity of light in media remains a major challenge in the field of optics. For the design of plasmonic slow light structures, graphene represents an attractive alternative to metals due to its strong field confinement, comparably low ohmic loss and versatile tunability. Here we propose a novel nanostructure consisting of a monolayer graphene...
متن کاملGraphene Oxide Based Surface Plasmon Resonance Biosensors
Graphene oxide (GO), an amorphous insulatormaterial, has consists of a hexagonal ring based carbon network having both sp2-hybridized carbon atoms and sp3-hybridizedcarbons bearing hydroxyl andepoxide functional groups on either side of the sheet, whereas the sheet edges are mostly decorated by carboxyl and carbonyl groups [1-6]. These unique properties hold great promise for potential applicat...
