For the first time, we use a single PCSEL as a light source, directly projected onto a designed holo-patterned metasurface. This results in a structure 233 times smaller than an iPhone＇s, without needing a lens system. This architecture, homogeneously integrated with photonic crystal lasers, reduces power consumption by 10.8 times compared to conventional systems. This innovation achieves miniaturization, lightweighting, and energy saving, making it easier to integrate into AR/VR systems.

Our structured light achieved 0.47° resolution, area size and power consumption is smaller 233 times and 10.8 times than commercial dots projector in iPhone.

Our ultra-thin metasurface nanophotonics technology has achieved a revolutionary leap in optical component design, enhancing performance while significantly reducing energy consumption and component size. This provides essential technical support for the integration of smart devices and systems across various industries, such as depth sensing, computer stereovision, posture sensing, and facial recognition.
