Analysis
This paper introduces a novel all-optical lithography platform for creating microstructured surfaces using azopolymers. The key innovation is the use of engineered darkness within computer-generated holograms to control mass transport and directly produce positive, protruding microreliefs. This approach eliminates the need for masks or molds, offering a maskless, fully digital, and scalable method for microfabrication. The ability to control both spatial and temporal aspects of the holographic patterns allows for complex microarchitectures, reconfigurable surfaces, and reprogrammable templates. This work has significant implications for photonics, biointerfaces, and functional coatings.
