Metamaterial is an artificial material composed of subwavelength micro nano structural functional units in a specific sequence. With unique electromagnetic characteristics and flexible design freedom, it is a research hotspot in the field of micro nano optics and a new platform for light field regulation. With the development of micro/nano optical technology, as a two-dimensional planar super structured material, the super structured surface has the advantages of lightweight, integration, multi-function and compatible with semiconductor preparation process, which is pushing the optical control elements into the "era of planar optics". Research on optical hyperstructured materials and hyperstructured surfaces has been rated as one of the top ten scientific and technological breakthroughs by science for many times. The US Department of defense has included it in one of the "six disruptive basic research fields", which has great application potential in advanced imaging and sensing, machine vision, virtual reality and augmented reality, intelligent optical computing, full-color display, quantum information and other fields.
Facing the national strategic needs and the forefront of optoelectronic technology, the research team used optical hyperstructured materials and hyperstructured surfaces to manipulate the multi-dimensional optical properties at the micro nano scale, studied the physical processes and laws of the interaction between artificial composite micro nano structures and different optical parameters (including frequency, phase, polarization, amplitude, propagation direction, angular momentum, pulse width, etc.), explored the new mechanism of the joint regulation of multi-dimensional light field information, and studied the design methods of hyperstructured materials and hyperstructured surfaces with different functional elements and spatial order structures according to the specific light field regulation requirements, so as to realize the accurate construction, regulation and characterization of multi-dimensional light fields. Aiming at the micro and nano structures with different materials, shapes and sizes, and guided by the compatible semiconductor process, the fabrication and integration of low-cost, large-area and high-precision optical devices made of super structured materials are studied. The research team has made a series of research achievements in the fields of complex spatio-temporal structure light field generation and regulation, new multi-dimensional imaging, detection and sensing, high-performance full-color display, optical simulation and image processing, optical information encoding and encryption based on optical hyperstructured materials or hyperstructured surfaces, which is expected to provide a physical basis for the cross application of planar optical devices in the fields of information, materials, life and so on, and provide basic and forward-looking scientific and technological reserves for the sustainable development of the national economy and national security.
The research team has more than 10 professors and full-time researchers, including 5 national high-level talents, including Nature、Nat. Nanotech.、Nat. Commun.、Sci. Adv.、Light Sci. Appl.、Phys. Rev. Lett.、Adv. Mater.、Nano Lett.、Laser Photon. Rev. And other journals published more than 100 papers. It has undertaken a number of research projects and topics such as the national key R&D plan, kjw key projects, the National Natural Science Foundation of China, and the natural science foundation of Jiangsu Province. Relevant research achievements have won the first prize of the Natural Science Award for scientific and technological innovation of the Chinese Optical Society, the annual progress of global optics of the American Optical Society, the top ten progresses of Chinas optics, and the outstanding scientific papers of the Chinese Association for science and technology.
