Abstract :
We propose the incorporation of graphene to integrated coupled resonator waveguides and side-coupled integrated spaced sequence of resonator devices to enable reconfigurable operation. The key element to achieve this is a tunable silicon graphene Mach-Zehnder interferometer (MZI) that acts as an equivalent variable 2 × 2 coupler, where the value of its coupling constant is changed by varying the chemical potential of a graphene section placed on top of one of its arms.
