a, Concept of zonal illumination. Zonal illumination can enhance image contrast and efficiency by turning on the illumination only where needed. It can be realized by using active PIC modulators. b, Schematic of a PIC-enabled holographic display. The PIC provides a tailored illumination field, which feeds into one or several layers of spatial light modulators (SLMs) for hologram generation. A flat lens, such as a holographic optical element, is then used to project and magnify the image.
