    Area of Science:

    • Photonics and Optical Engineering
    • Materials Science

    Background:

    • Variable optical attenuators (VOAs) are crucial components in optical communication systems for managing signal power.
    • Existing VOA technologies often face limitations in terms of size, power consumption, or attenuation range.

    Purpose of the Study:

    • To develop and characterize compact, electrically controlled fiber variable optical attenuator arrays using polymer-network liquid crystals.
    • To assess the performance metrics including attenuation range, residual loss, power consumption, and scalability of the developed attenuator arrays.

    Main Methods:

    • Fabrication of attenuator arrays by creating trenches in conductive-layer-coated optical fibers and filling them with polymer-network liquid crystals.
    • Electrical control of optical attenuation through the liquid crystal properties.
