    Summary
    This summary is machine-generated.

    Researchers generated curved light beams called photonic hooks (PHs) using Janus microcylinders. This new method offers tunable PHs with a narrower focus than traditional photonic nanojets.

    Area of Science:

    • Optics and Photonics
    • Microparticle Physics
    • Nanotechnology

    Background:

    • Photonic hooks (PHs) are curved light beams resulting from broken symmetry in microparticles illuminated by plane waves.
    • Previous methods relied on structural asymmetry for PH generation.

    Purpose of the Study:

    • To present a novel approach for generating PHs using material composition asymmetry in Janus microcylinders.
    • To investigate the characteristics and formation mechanisms of PHs generated from Janus microcylinders.

    Main Methods:

    • Utilized the Finite Element Method (FEM) for numerical simulations.
    • Employed energy flow analysis for theoretical investigation of field distribution.
    • Investigated Janus microcylinders with varied refractive index contrasts and orientations.

    Main Results:

    • Generated PHs from Janus microcylinders by exploiting material composition asymmetry.
    • Achieved a narrower Full Width at Half Maximum (FWHM) for PHs (∼0.29λ) compared to photonic nanojets (∼0.35λ).
    • Demonstrated efficient modulation of PH shape by altering refractive index contrasts and Janus microcylinder rotation.

    Conclusions:

    • Janus microcylinders provide a versatile platform for generating tunable photonic hooks.
    • The proposed method offers enhanced control over PH properties, including shape and focus.
    • Tunability was further demonstrated through mechanical stretching/compression of hybrid inorganic-polymer Janus microcylinders.
