Abstract

Flat optics with micro-nano structures fabricated on a flat substrate is promising for integrated optics for its compactness and compatibility for large volume manufacturing. In this talk, I will introduce our works on photon nano sieves with holy structures for polarization independent broadband high diffraction efficiency and large angle-of-view hologram, specially designed Fresnel flat lens to break the diffraction limit for higher resolution focusing and imaging, phase change materials and emerging 2D materials for reconfigurable and ultra-thin flat lens demonstration, and applications of these flat optics in lithography, medical imaging and optical data storage.
