Fig. 4: Demonstration of two basic functionalities using the fabricated PI-LCoS device.

a–d Schematic of beam steering (a) and the measured optical intensity distributions of different linearly polarized light after beam steering with diffraction angles from 1° to 4° (b). All images have the same intensity reference and position reference. Quantitative analysis of the beam-steering performance with total efficiency and polarization dependence (c) for different linearly polarized light with polarization angles at every 15° between 0° to 180° (0° corresponds to the direction of LC directors) (d). Holographic imaging of ‘4 K PI-LCOS’ logo (e) by the PI-LCoS (f) and the original LCoS (g) under two orthogonal linearly polarized input light (0° and 90° polarization). The scale bar for these holographic images is 5 mm in size
