Sub‐Diffraction and Irreversibly Tunable Imaging With Potato Starch Lenses

Biological microstructures offer sustainable and functional platforms for photonic applications. In this work, potato starch granules are shown to act as natural microlenses, capable of modulating both the dynamic and geometric phases of light. Their intrinsic radial birefringence and spherical shape enable simultane...
