A Perspective on Continuous Superlattices and Device‐by‐Design Pathways Toward Electrically Driven Perovskite Lasers and Cooperative Emission

Halide perovskites are emerging optical gain media; however, electrically assisted lasing is currently prohibited by Joule heating, ion migration, injection imbalance, high‐density non‐radiative recombination, and contact‐related optical losses. This Perspective summarizes recent progress on optically pumped micro‐ and nanolasers and identifies materials and resonator architectures relevant to electrical operation. We further distinguish current‐induced lasing from superradiance and superfluorescence stemming from cooperative exciton emission. We then consider continuous perovskite superlattices containing experimentally verified periodic electronic potentials, as a proposed platform for controlling carrier transport, energetic disorder, and optical transitions. If such architectures also preserve coherent and spectrally homogeneous exciton synchronization, they may support transient cooperative emission. Steady‐state bad‐cavity cooperative lasing is a distinct, more demanding objective requiring common‐mode synchronization and repumping that sustains collective coherence. By separating established demonstrations from proposed materials concepts, we outline a materials‐ and device‐design roadmap toward electrically driven perovskite lasers and cooperative light sources.
