摘要

Naked-eye 3D micro-LED display combines the 3D characteristics and advantages of micro-LED simultaneously. A conventional micro-LED device emission exhibits Lambertian distribution, and it requires stacking of multiple optical components into a 3D display, resulting in bulky systems, low efficiency, and a limited viewing zone and points. We propose and investigate a single-chip micro-LED with unidirectional emission through an in-situ integrated resonant cavity and metasurface, which has great potential to be used for an efficient naked-eye 3D display with a wide viewing angle and multiple viewpoints. This Letter promotes the application of GaN-based micro-LEDs in a display, especially a 3D display. (C) 2021 Optical Society of America
