Information technology has entered into the nanometer scale era. Nano-optics and photonics are generated and developed to meet the demands of fast and high density information technology. Advanced nano-optical and photonic devices should be of high speed, high resolution and high integration, forming various types of optical and photonic chips and disks. Because the minimum feature size and processing resolution of optical devices are limited by the diffraction limit, the existing technologies have been approaching to the theoretical limit and the cost is very high. Only breaking through the diffraction limit can further develop nano-optics and photonics. Achieving super-resolution in the far and near optical fields is one of the important academic topics, and its application is mainly focused on the optical super-resolution technologies for the nano information storage and lithography applications.
