Fig. 5: Multifunctionality and cascaded metasurfaces.

From: Infrared beam-shaping on demand via tailored geometric phase metasurfaces employing the plasmonic phase-change material In3SbTe2

Fig. 5

A Superimposed phase masks of the hologram, magnifying lens, and beam steerer leading to the phase mask of the metasurface for enlarged and deflected holography. B Measured intensity profiles of the corresponding metasurface. The incident LCP light is attenuated and visible at 0°, while the “ir nano” hologram appears deflected at 10°. C Sketch of the measurement setup for cascaded metasurfaces creating the OAM at 0° (optional) and the deflected and enlarged hologram at 10°. D Measured OAM intensity profile at 0° and deflected hologram at 10°.
