Bilayer Graphene Optical Modulator Based on Metal-Nanoribbon Integrated Hybrid Plasmonic Waveguide

Abstract:

This study presents a novel contribution to the research of graphene-based electro-optic modulators. In this paper, we numerically demonstrate an ultra-compact and efficient graphene modulator based on metal-nanoribbon integrated hybrid plasmonic waveguide. Benefiting from the good in-plane mode polarization matching and strong hybrid surface plasmon polariton and grapheme interaction, the 10 μm-length modulator can achieve good modulation performance with a wide modulation bandwidth of 41.3 GHz and a low energy consumption of 101 fJ/bit at 1.55 μm. These compact and energy-efficient optical modulators may have broad application prospects in the future optical communication systems.
