Abstract

Here a novel modulator design containing a graphene double layer based on the Fabry-Perot interferometer is designed and fabricated. This proposed device bypasses the power consumption problem by enhancing the optical absorption in graphene through enlarging the interaction of light with graphene layers by > 40-fold compared with conventional designs. Due to the direct dependency of applied voltage with respect to the absorption in graphene, sub-volt operation with an adequate modulation depth (>5 dB) is expected from this device. Only few fJ/bits power consumption is required to ambulate the Fermi-level from Dirac to the desired point in Pauli Blocking mechanism.
