How to realize achromatic metalens with varifocal performance?The recently proposed broadband achromatic metalens (BAM) have been considered as a promising method to correct chromatic aberration in broadband imaging systems. However, these BAMs are limited to a fixed functionality that severely hinders their potential... Metalens, one of the most prominent applications of metasurface, has demonstrated the promising abilities to replace traditional lens. By manipulating the phase distribution of metalens composed of appropriately arranged meta-atoms, the wavefront of inciden...May 16, 2023 -

Harnessing the ‘virtual’ electromagnetic momentum for real object manipulationIn a recent study published on PNAS, a research team at the State Key Laboratory of Transient Optics and Photonics, Xi'an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences (CAS) , together with other three teams at Jinan University, t...Nov 07, 2022 -
Rapid full-color Fourier ptychographic microscopy provides a new solution for digital pathologyFourier ptychographic microscopy (FPM) is a promising computational imaging technique to realize high-throughput pathological imaging in medical diagnosis. However, existing FPM colorization approaches suffer from a trade-off between color precision and eff...Oct 13, 2022 -
Are there any realizable approaches for generating electromagnetically induced moire optical lattices?Electromagnetically induced transparency (EIT) effect is normally originated from a quantum interference occurring in three-level atomic systems and it is one of the important research objects in quantum optics. The EIT effect can provide a narrowband trans...May 19, 2022
