Polarization Optics: Versatile Polarization Generation and Manipulation Using Dielectric Metasurfaces (Laser Photonics Rev. 14(11)/2020)

In article number 2000116, Fei Ding, Sergey I. Bozhevolnyi, and co-workers demonstrate a versatile strategy for efficiently generating arbitrary polarization states with controllable wavefronts from a linearly-polarized light source with dielectric metasurfaces. Advanced polarization and wavefront manipulation functionalized to realize a polarization-resolved multifocal metalens and the vectorial holographic display is accomplished using segmented metasurface sub-arrays capable of manipulating, simultaneously and independently, both polarization and phase of the transmitted beams. This concept provides opportunities to develop a complete set of flat polarization optics for integrated photonics and quantum optics.
