Abstract
In a three-level system, actively detuning coupling strength between the respective waveguide modes via electrically gating the graphene double-layer allows ultra-fast switching of light propagating through the outer waveguides. In adiabatic elimination regime, the amplitude of the middle waveguide oscillates much faster in comparison to the outer waveguides leading to a vanishing field build up. As a result, the middle waveguide becomes a dark state and hence a low insertion-loss of 1 dB is obtained. Due to the direct dependency of applied voltage with respect to the absorption in graphene, sub-volt operation with modulation-depth of 5 dB is expected.
