Spin‐Orbit Photonics with Potato Starch Lenses

open access: yesAdvanced Optical Materials, EarlyView.
Native potato starch spherulites are introduced as volumetric optical elements that modulate both dynamic and geometric phases of light. These spherulites focus light and generate optical vortices via spin‐orbit interaction, functioning as polarization‐sensitive microlenses. Their unique radial anisotropy enables applications in vortex beam generation,
