Dual-Channel Graphene-Based Optical Switch

Abstract

In this article, we have shown dual channel optical switching of two Fano resonances by varying graphene's Fermi potential at telecommunication wavelengths of 1.53 µm and 1.57 µm. The two optical switches can be controlled independently; hence we have shown four possible combinations of the switch: “on-on, on-off, off-on, off-off.”
