Abstract
A lens system having reduced physical size. The lens system includes multiple metalenses, lenses with metasurfaces, that integrate the lens and the free space and compress them into multiple layers of metasurfaces, significantly reducing the overall volume and weight of the imaging system while increasing its efficiency. The lens system also provides for tools that can accurately model 3D multilayer metasurfaces, carry out inverse design to find the optimal and fault-tolerant structure, fabricate the metasurfaces with multi-project wafer service, assemble them with a 3D-printed holder, and characterize the performance of the resulting ultra-compact imaging system.
