  • Simulation of dielectric-loaded surface plasmon polariton waveguides (DLSPPWs) with varying ridge materials and spacer dielectrics.
  • Calculation of modulation depth, energy per bit, and figure of merit (extinction ratio/insertion loss).
  • Analysis of wavelength dependence and gate voltage effects on graphene conductivity and waveguide attenuation.

    • Main Results:

    • Achieved 3 dB modulation with a 65 nm-long DLSPPW waveguide, yielding an energy per bit of 0.08 fJ/bit.
    • Figure of merit improved from 5.2 (low index ridge) to 17.3 (Si ridge), significantly outperforming photonic graphene waveguides (3.5).
    • Long-range DLSPPWs (LR-DLSPPWs) showed a figure of merit exceeding 72, with 3 dB modulation achieved in 10 μm waveguides (15.8 fJ/bit).
    • Gate voltage tuning shifted attenuation curves, enabling >15 THz bandwidth in a 12 μm DLSPP waveguide.

    Conclusions:

    • Dielectric-loaded plasmonic waveguides offer a promising platform for high-performance graphene-based electro-optic modulators.
    • Optimized ridge materials and waveguide designs significantly enhance modulation efficiency and reduce energy consumption.
    • The proposed modulators demonstrate potential for ultra-compact and energy-efficient optical communication systems.
