Quantum Dots on Flexible Nanohole Arrays Support Stable Nanolasing

Shaobin Zheng, Qinglin Ji, Yuehua Chen, Wei Shao et autres

Nanostructure lattices offer a compact platform for small, coherent light sources but suffer from compromised emission stability under mechanical deformation. In this study, we demonstrate a flexible nanolaser comprising a perovskite quantum dot (QD) film and a polydimethylsiloxane (PDMS) nanohole array filled …

Surface Lattice Resonances Enable Spatially Unified Perovskite Lasing

Jingyue Yu, Xinyu Wen, Qinglin Ji, Kangkang Guo et autres

Abstract Plasmonic‐perovskite heterostructures offer a compelling platform for nanolasers but face challenges in operational reproducibility as previous methods require precise pumping regions. Here, hybrid Ag/perovskite lattices is demonstrated that enable spatially unified lasing across the entire lattice with low thresholds, thereby eliminating …

Large-Area Perovskite Nanocrystal Metasurfaces for Direction-Tunable Lasing

Nanli Mou, Bing Tang, Bowen Han, Jingyue Yu et autres

Perovskite nanocrystals (PNCs) are attractive emissive materials for developing compact lasers. However, manipulation of PNC laser directionality has been difficult, which limits their usage in photonic devices that require on-demand tunability. Here we demonstrate PNC metasurface lasers with engineered emission angles. We …
