The Role of AI in DOE Design

Designing a Diffractive Optical Element is a complex task involving the precise arrangement of microstructures that manipulate light into desired patterns. Traditional methods rely heavily on iterative simulations and trial-and-error processes. AI, particularly machine learning and deep learning, enables faster and more accurate predictions, automating much of the labor-intensive design work.

With AI-driven algorithms, engineers can input specific performance criteria, such as diffraction efficiency, wavelength, and angle of incidence, and let AI find the optimal microstructure pattern. The result is a DOE design that meets exacting standards in a fraction of the time previously required.
