    Area of Science:

    • Optics and Photonics
    • Materials Science
    • Nanotechnology

    Background:

    • Metasurfaces offer advanced optical functionalities but typically lack electronic tunability.
    • Fixed diffractive waveplates limit applications requiring dynamic optical control.
    • Liquid crystals provide a tunable medium for optical devices.

    Purpose of the Study:

    • To experimentally demonstrate an electrically switchable diffractive waveplate using metasurfaces and liquid crystals.
    • To analyze the efficiency limits of such liquid crystal-based diffractive waveplates.
    • To assess the stability of the device across different wavelengths and temperatures.

    Main Methods:

    • Fabrication of a single-layer device combining metasurfaces with tunable liquid crystals.
    • Experimental measurement of diffraction efficiency and switching voltage.
    • Computational analysis of theoretical efficiency limits.
    • Testing device performance under varying wavelengths and temperatures.

    Main Results:

    • Achieved electrically switching of a diffractive waveplate design.
    • Measured a peak diffraction efficiency of 35%.
    • Demonstrated a minimum switching voltage of 10V.
    • Observed device performance largely independent of wavelength and temperature variations.

    Conclusions:

    • Successfully created a tunable diffractive waveplate with liquid crystals and metasurfaces.
    • The device exhibits robust performance across different environmental conditions.
    • This technology opens possibilities for dynamic thin film beam steering, tunable lenses, and polarization filters.
