Airy beam applications such as optical trapping, micro-machining, and imaging microscopy have garnered significant attention in recent years. This research introduces a comprehensive methodology for the design, simulation, fabrication, and evaluation of micro-binary diffractive optical elements aimed at generating Airy beams. First, a binary pattern is meticulously designed by means of computergenerated holography. Subsequently, the optical performance of the pattern is simulated using a Fresnel impulse response propagator, which is rooted in the Rayleigh–Sommerfeld diffraction in Fourier optics. Following this, a laser writing path is generated through a machine learning decision tree algorithm. A multifunctional direct laser lithography system is then used to fabricate the pattern. Lastly, a meticulous assessment of the surface quality is conducted, and an optical verification system is established to confirm the optical performance. This holistic process is characterized by its simplicity, self-contained nature, and cost-effectiveness due to its independence from masks, unlike traditional methods such as photolithography, ensuring a high level of accuracy. Moreover, it is important to note that this process is not only suitable for fabricating Airy beam diffractive optical elements, but also has the potential to generate other binary diffractive optical elements, notably on the micro-scale.
