A plasmonic-hybrid-waveguide-based optical phase modulator is proposed and analyzed. The field enhancement in the low-index high-nonlinear polymer layer provides nanoscale optical confinement and a fast optical modulation speed. At 2.5 V drive voltage, a π phase shift can be obtained for a 13 - μm -long plasmonic waveguide. Because of its small capacitance and parasitic resistance, the modulation bandwidth can reach up to 100 GHz with a low power consumption of 9 fJ / bit . The plasmonic waveguide is connected to a silicon wire waveguide via an adiabatic taper with a coupling efficiency of 91 % . The phase modulator can find potential applications in optical telecommunication and interconnects.
