Optical On-Off keying based on graphene has received great attention in the past years for communication applications. However, most studied devices suffer from a low extinction ratio. Here we introduce a design based on the integration of graphene (two layers of graphene with a dielectric in between) on a silicon slot waveguide. It has an extinction ratio over 20 dB for a 100 um device length with an applied voltage of 6 Volt and operates with TE polarized light. The insertion loss, another key parameter for optical switches, is only 1 dB, assuming high quality graphene.
