Abstract
While phased-array metasurfaces have been used extensively for wavefront shaping of coherent light, their capability to control spontaneous emission is an open question. Here, we demonstrate metalenses that emit focused beams and compare the focusing performance across different devices. The developed concepts open new possibilities for development of versatile light sources.
