Chinese Optics Letters (COL) invites high quality articles for a Special Issue on Optical Metasurfaces: Fundamentals and Applications to be published in Jan. 2023. Optical Metasurfaces are ultrathin optical designs composed of subwavelength meta-atoms, and have demonstrated unprecedented capabilities in manipulating light propagation. After tremendous research during the past decade, the working principle of metasurfaces has be extended from initial resonance of meta-atoms to non-resonant geometric phase and dynamic propagation phase. The constituent materials have been extended from metals to dielectrics to further reduce the loss, and make the high-efficiency devices more applicable. By now, numerous functionalities have been realized, such as beam engineering, waveplates, polarizers, holograms, metalenses, and so on. People are expecting a new version of metasurface 2.0 that will not only enrich the frontiers of optical sciences but also revolutionize the traditional optical devices and technology in real applications.

The Special Issue is intended to present recent advances in optical metasurfaces, from the function-oriented new designs to cutting-edge applications. All interested authors are invited to submit their newest results for possible publication in this Special Issue. All manuscripts need to present original, previously-unpublished work and will be subject to the normal standards and peer-review processes of this journal. Specific areas of interest include but are not limited to:

● Metasurfaces for light manipulation

● Metalenses for imaging technology

● Metasurfaces for nonlinear and quantum optics

● Multifunctional metasurfaces

● Intelligent metasurfaces

● Active and tunable metasurfaces

● perfect absorbers
