    This study introduces a new method for creating high-quality optical vortices using multilevel vortex-producing lenses (VPLs). This technique enhances optical vortex quality, even with limited phase levels on spatial light modulators.

    Area of Science:

    • Optics and Photonics
    • Light Manipulation
    • Vortex Beam Generation

    Background:

    • Optical vortices are crucial for applications like optical trapping and quantum information.
    • Generating high-quality optical vortices often requires complex phase elements and high-resolution devices.
    • Liquid-crystal spatial light modulators (SLMs) offer flexibility but have limitations in projecting phase levels.

    Purpose of the Study:

    • To propose and validate a novel method for generating high-quality optical vortices.
    • To overcome the limitations of phase level capacity in spatial light modulators.
    • To improve the quality of optical vortices produced using multilevel phase elements.

    Main Methods:

    • Implementation of multilevel vortex-producing lenses (VPLs) on a liquid-crystal spatial light modulator.
