چکیده :

Abstract—Electro-optic modulators play a substantial role in modulating high-speed optical signals in photonic integrated systems. Graphene is a very promising material for various optoelectronic applications, allowing the realization of active optical devices. Plasmonic waveguides are the most promising candidates for subwavelength optical confinement. We propose a graphene-based electro-absorption modulator integrated with hybrid plasmonic waveguides. The proposed configuration integrates the benefits of both graphene and plasmonic waveguides. The results demonstrate that the modulation depth of our proposed modulator can reach 1.0917 dB/μm at low gating voltages with a wavelength of 1.55 μm. When compared with previous papers, our proposed modulator shows superior performance.
