Bends and splitters in graphene nanoribbon waveguides
Xiaolong Zhu, Wei Yan, N. Asger Mortensen +1
We investigate the performance of bends and splitters in graphene nanoribbon waveguides. Although the graphene waveguides are lossy themselves, we show that bends and splitters do…
Quantum optical effective-medium theory for loss-compensated metamaterials
Ehsan Amooghorban, N. Asger Mortensen, Martijn Wubs
A central aim in metamaterial research is to engineer sub-wavelength unit cells that give rise to desired effective-medium properties and parameters, such as a negative refractive…
Graphene plasmon polaritons: Substrate effects and nonlocal response
Thomas Christensen, Antti-Pekka Jauho, N. Asger Mortensen
This paper is withdrawn by the authors. We theoretically examine graphene plasmon polaritons (GPP) supported by a sheet of graphene sandwiched between two dielectric media. The inf…
Fundamental limitations to gain enhancement in periodic media and waveguides
Jure Grgić, Johan Raunkjær Ott, Fengwen Wang +4
A common strategy to compensate for losses in optical nanostructures is to add gain material in the system. By exploiting slow-light effects it is expected that the gain may be enh…
