Optical microscopy provides a revolutionary technique for wide fields such as life science, medicine, and microelectronics. However, if the technique can not break the bottleneck of 100 nm spatial resolution in the far field, its advantages would be hard to further reflect in high-speed developing wide fields. This project will focus on the fundamental theory and applications of far-field nano-optical imaging devices with feasible potential and overcoming the shortcomings of the present far-field nano-optical imaging techniques, to construct a theoretical model for understanding the propagation of feature size below 80nm in free space, to design structures for modulating and controlling the propagation of optical field containing nanostructures and to study their physical mechanism and characteristics, and finally to search for imaging methods both numerically and optically. The key scientific and technological problems needed to solve include: 1) Theoretical basis for far-field nano-optical imaging in the case of the optical information propagating in free space. 2) Properties and modulation and control of optical signals containing nanostructures in the far field. 3) Structure design of devices for far-field nano-optical imaging. 4) Methods for far-field nano-optical imaging and principle demonstration. Through the researches of this project, we hope to realize the design and fabrication of far-field nano-optical imaging devices with spatial resolution super over 80 nm, and to hold leading and creative fruits with independent intellectual property rights, and to provide novel and key components for wide applications of nano-optical imaing techniques.
