Figure 2. Experimental verification of the waveguide-based six-channel metahologram.

Caption

(a) Schematic diagram of the experimental system for single-color imaging. (b) Experimental results of the waveguide-based six-channel metahologram.  Six crosstalk-free holographic images (capital letters “A” to “F”) are selectively projected when the metahologram is illuminated by a guided incident light with different azimuthal angles (0°, 60°, and 120°) and spin states (right circular polarization and left circular polarization).
