Fig. 5. Simulated tunable holograms with varying applied voltages in the xy plane with normal incident light. The metasurface is designed as a 100 × 100 array at a wavelength of 550 nm with a focal plane at 28 μm. A star-shaped hologram is illustrated at an incident wavelength of 488 nm at applied voltages of (a) −8.9 V and (b) −33.7 V. Star hologram demonstrated for the incident wavelength of 633 nm at an applied voltage of (c) −8.9 V and (d) −33.7 V.
