Metalens Doublets: Spin Angular Momentum Controlled Multifunctional All‐Dielectric Metasurface Doublet (Laser Photonics Rev. 14(6)/2020). Issue 6 (15th June 2020) - Yu, Lieguo
Abstract : In article number 1900324, Shumin Xiao, Qinghai, Song and co‐workers demonstrate a multi‐functional metalens doublet. By combining two metalenses for circular‐polarized light and non‐polarized light into a group, the function of the system can switch between camera lens, compound microscope, and Galileo telescope via the control of incident polarization and separation distance.
