We propose and investigate a 2 × 2 optical switch based on multimode interference in Au-Air-Au gap plasmonic waveguide. The propagation of surface plasmon wave in gap plasmonic waveguide could be tuned by changing the size of air gap through a nanomechanical actuator. By tailoring the dispersion of...
