Hybrid metasurface-refractive system achieves wide field of view in an ultracompact volume, suggesting new possibilities in optical design.
Hybrid metasurface–refractive systems have often raised concerns about their overall volume and the complexity of mechanical alignment. This reported study presents a fully integrated meta-aspheric optical system that realizes a wide field of view within an ultracompact volume of 0.02 cm 3 .
