Exciton–Polariton Effect and Polarized High‐Quality Lasing in 1D CsPbBr ₃ ‐CsPb ₂ Br ₅ Perovskite Planar Microcavities via Solution‐Driven Soft Thermal Imprinting (Advanced Optical Materials 10/2026)

Perovskite Planar Microcavities Solution-imprinted CsPbBr3–CsPb2Br5 perovskite microwires achieve high-Q lasing, strong exciton–polariton coupling, and highly polarized waveguide modes. Their robust heterointerfaces and enhanced exciton binding enable low-cost, high-performance microcavity photonic devices with promising nonlinear and polarized lasing applications.
