Perovskite Lasers and Optoelectronic Devices

Metal halide perovskites have revolutionised optoelectronics through their unique combination of facile solution processing, tunable bandgaps and exceptional optical gain. Their crystalline ABX₃ lattice endows them with high photoluminescence quantum yields, low lasing thresholds and strong light–matter interactions across the visible spectrum. In laser research, perovskites have been demonstrated in whispering-gallery-mode microcavities, distributed feedback resonators and vertical-cavity surface-emitting architectures. Quantum-confined variants such as nanocrystals and quantum dots further boost excitonic emission and enable single-mode, low-threshold lasing. Advances in fabrication—including nanoimprinting, laser patterning and topological cavity design—yield reproducible microlaser arrays and robust devices tolerant of structural imperfections. Concurrently, perovskite photodetectors, light-emitting diodes and nonlinear metasurfaces leverage the same material platform for integrated optoelectronic applications, from on-chip optical interconnects to high-resolution displays and quantum light sources. Sustainable synthesis and lead-free compositions remain active areas, as the community seeks scalable, stable and eco-friendly perovskite photonic technologies.

Research from Nature Portfolio

Recent studies have exploited topological photonic concepts to engineer ultrathin, vertical-emitting perovskite quantum dot lasers that combine low thresholds with resilience to fabrication defects. By interfacing one-dimensional photonic crystals with distinct Zak phases, a lithography-free topological cavity confines the gain medium within few monolayers of cesium lead halide quantum dots, yielding single-mode green emission akin to vertical-cavity surface-emitting lasers. Foundational work on colloidal caesium lead halide nanocrystals demonstrated room-temperature amplified spontaneous emission across the visible range with modal gains exceeding 450 cm⁻¹ and whispering-gallery-mode lasing in microsphere resonators. More recently, phase-stable perovskite thin films have achieved continuous-wave amplified spontaneous emission at cryogenic temperatures, marking a critical step towards sustained lasing by maintaining structural phase integrity under CW excitation.
