title = "Stable Single-Mode Lasing from a Hybrid Perovskite–Polymer Fiber",
abstract = "Nanowire lasers are potential light sources that can be used in photonic integrated circuits (PICs) for inter-chip optical communication. However, due to the size incompatibility between a nanoscale laser and a micrometer-scale optical waveguide, their integration within a PIC remains challenging. Here, an in situ growth strategy to directly construct perovskite nanolasers inside the long polymethyl methacrylate (PMMA) fibers is explored. As the perovskite nanolasers are embedded inside the PMMA fibers, effective coupling of lasing light to the PMMA fibers is expected. Furthermore, due to the protection of PMMA coating, the perovskite nanolasers exhibit high robustness in water and demonstrate significant improvement in photostability. Stable single-mode and polarization operations are obtained at room temperature from the lasers with a low excitation threshold. Hence, these results pave the way to realize ultra-stable perovskite-based PICs suitable for inter-chip optical communication.",
