  • Text, image, and hologram projection experiments validated the SMLA performance.

    • Main Results:

    • A flexible SMLA with circular nonostepped pyramids in hexagonal arrangements was successfully fabricated.
    • The SMLA demonstrated efficient bidirectional light focusing with a maximum numerical aperture (NA) of 0.60.
    • Distance-dependent narrow-band light focusing was achieved, influenced by nanostep dimensions and quantity.

    Conclusions:

    • Imprinted bidirectional SMLA on flexible substrates offer promising performance for optical systems.
    • The fabrication method enables mass production of nanophotonic devices for displays and portable sensors.
    • Tunable photonic bandgaps and distance-dependent focusing highlight the versatility of these nanostructures.
