In this paper, a numerical investigation has been performed on the limits of miniaturization for a graphene-assisted modulator considering two different configurations, in both cases the critical coupling condition representing the OFF state, and the transmission level of − 3 dB the ON state. In addition, the power consumption per bit of 100 fJ/bit was established as the cutoff parameter for both modulator configurations, as well as the minimum chemical potential for the ON state of 0.4 eV for the hybrid modulator. Considering the parameters aforementioned, our results showed that both configurations of modulators have great potential of miniaturization, high modulation speed and low power consumption.
