Abstract
The present inventions is related to the optical lenses that use subwavelength structures to perform an optical function, the applications of such lenses, and the methods of making the same. Particularly, the present invention provide an optical lens(es), termed “subwavelength Moiré index lens” or “SMIL” for manipulating light. The SMIL comprises a thin material layer having an effective optical index that has a Moiré pattern of two or more periodic structures. The SMIL allows a lens to be ultrathin, flat, numerical aperture nearly one, scalable to large area, and manufacturable at low cost. The present invention also provides the systems based on SMIL, such lens systems, LEDs and photodetectors, and the fabrication methods of the SMIL.
