Bends and splitters in graphene nanoribbon waveguides

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 not induce any additional loss provided that the nanoribbon width is sub-wavelength. We use transmission line theory to qualitatively interpret the behavior observed in our simulation.

Our results pave a promising way to realize ultra-compact devices operating in the terahertz region.
