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…

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…
