Abstract

Optical modulation is an essential process in the telecommunication technology. A sub-femtojoule optical modulation based on low loss hybrid plasmonic waveguide which integrates silicon, metal, and electro-optic material is demonstrated. Modulation is achieved through applying modulating voltage across the electro-optic layers. Firstly, a directional coupler modulator is designed and simulated, it showed a modulation depth of 26 dB, and energy consumption of 0.8 fJ/bit. Secondly, a Mach Zender interferometer circuit based modulator is designed and analyzed, with a modulation depth of 32 dB, and energy consumption of 0.8 fJ/bit.
