Circularly polarized light emission from a GaN micro-LED integrated with functional metasurfaces for 3D display

This Letter proposes a circularly polarized (CP) light GaN micro-LED which is integrated with functional metasurfaces. The one-dimensional metallic nanograting can achieve a high transverse electric (TE) reflectivity ( R T E ) and extinction ratio (ER) of TE and transverse magnetic (TM) waves, which...
