Ge2Sb2Se4Te1-based spin-decoupled metasurface for multidimensional and switchable focusing in the mid-infrared regime

Metalens is an ultrathin flat optical device with a great potential for applications in spin-controlled nanophotonics. However, most advanced metalenses typically work at a single wavelength or one specific spin state of incident light, hindering their applications in practice. In the present work,...
