Abstract

Automatic optimization of diffractive structures is of great interest and has potential applications in see-through near-eye displays. Here, we propose an approach of on-demand design of diffractive elements using the physics-driven topological optimization. The topology is iteratively optimized according to the added constrains in dispersion and angle uniformity. The proposed model provides an effective way for the design of complex electromagnetic components that are essentially irregular and out of the box of human’s designing.
