“…Compared with 3D metamaterials which are always limited by nano-processing technology and high optical loss, 2D meta-surfaces are easier to process and have relatively low optical loss, so it attracts much attention in the aspect of nonlinear optical field regulation [40]. As a result, the wavelength range limited of the laser light source can be expanded to the ultraviolet and deep ultraviolet area, and make up the cost of expensive laser infrared or ultraviolet light [41][42][43]. Andrew Forbes demonstrated the first meta-surface laser in the world which produced "super-chiral light": light with super high angular momentum [44].…”

Single photon light detection and ranging (LiDAR) has the advantages of high angle and distance resolution, great concealment, a strong anti-active jamming capability, small volume, and light mass, and has been widely applied in marine reconnaissance, obstacle avoidance, chemical warfare agent detection, and navigation. With the rapid development of metamaterials, the performance of a single photon LiDAR system would be improved by optimizing the core devices in the system. In this paper, we first analyzed the performance index of the single photon LiDAR and discovered the potential of metamaterials in improving the system performance. Then, the influence of metamaterials on the core devices of the single photon LiDAR were discussed, including lasers, scanning devices, optical lenses, and single photon detectors. As a result, we have concluded that through effective light field modulation, metamaterial technology might enhance the performance innovation of the single photon LiDAR.
