Abstract

We present a novel micrometer-sized intensity modulator based on a silicon-polymer hybrid plasmonic waveguide. The field enhancement in the low-index high-nonlinear polymer layer provides a nano-scale optical confinement and a fast optical modulation speed. After applying a voltage, the surface plasmon waves experience different phase delays, resulting in an intensity variation at the output waveguide. Due to its small capacitance and parasitic resistance, the RC delay time is <6 ps, corresponding to a modulation bandwidth of >40 GHz. The intensity modulator can find potential applications in optical telecommunication and interconnect.
