The ability to engineer optical phase response at subwavelength dimensions has led to passive metasurfaces that provide unprecedented control of electromagnetic waves. Recent demonstrations of metasurface-mediated photoluminescence highlight their potential for future device implementation. However, the lack of a phase-defining input wave introduces fundamental challenges to the design and implementation of metasurface light emitters. Here we demonstrate recent innovations in the design, optimization and fabrication of metasurface light-emitting devices.
Specifically, we demonstrate a GaN-based Quantum Well metasurface platform that supports metasurface-mediated light emission such as unidirectional or focused spontaneous luminescence. We detail methods to both simulate and optimize metasurface light emission, demonstrate electroluminescent metasurface light emitting devices (i.e., LEDs), and explore future design concepts for achieving new functionality and superior performance.
