Holographic lasing with dielectric metasurfaces

Light-emitting metasurfaces provide a compact, integrated solution for simultaneous light generation and beam shaping, making them a promising candidate for advanced photonic applications. However, existing approaches for tailoring far-field emission patterns either operate in the spontaneous emission regime, where low coherence limits precise light control, or rely on passive holographic metasurfaces that shape externally supplied coherent (or partially coherent) illumination. Here, we present a light-emitting metasurface system with holographic lasing output, composed of a binary-structured metasurface integrated with a gain medium, that enables coherent light generation and precise beam shaping of the output lasing emission within a single device. Through our design approach, the device sustains robust lasing performance despite structural disorder introduced for holographic encoding. With a compact ultraflat footprint, low lasing threshold, and wide field of view, our system offers an exceptional platform for generating design-specified structured lasing emission, with notable potential for miniaturized optical systems.
