  • Investigation of state conversion under normally incident optical pumping.

    • Main Results:

    • Achieved state conversion from dielectric to metallic photonic crystal (PC) due to VO2's IMT.
    • Demonstrated broadband intensity modulation with 70% modulation depth.
    • Observed state conversion from dielectric PC to a plasmonic device with partial VO2 IMT, leading to plasmonic resonances.

    Conclusions:

    • The developed plasmonic device enables efficient THz wave modulation through controlled state conversion.
    • The device's performance is directly linked to the insulator-metal transition of VO2.
    • This technology holds significant promise for future terahertz applications.
