中文摘要A structured lens with a large numerical aperture for high diffraction efficiency is proposed. This structured lens is formed by varying high-refractive-index-dielectric(HRID) square holes in a metallic film. Compared with previous structured lens is smoother and the diffraction efficiency is greatly impedance mismatching between air and the high refractive index dielectric. A lens with an aperture of 100um and a focal length of 50um was designed;its diffraction efficiency has been raised from 22.8%to 47.2% by the finite difference and time domain(FDTD)algorithm. This structured lens has the advantages of not only light weight and high compactness, ut also large numerical aperture,high diffraction efficiency,and good imaging quality.
