Abstract
We employ the plasmonic Phase-Change Material In3SbTe2 (IST) for direct laser-writing of functional infrared metasurfaces, without the need for cumbersome cleanroom fabrication. We demonstrate rapid prototyping of large area metasurfaces for controlling thermal emission, beam steering, lensing and also create IR holograms into IST films. Additionally, we combine laser-written IST structures with materials hosting surface waves to launch and confine Surface Phonon or Plasmon Polaritons into resonators.
