Circularly polarized lasers play a pivotal role in classical optics, nanophotonics, and quantum optical information processing, while their fabrication remains complex. This article begins with examining the interactions between stimulated emission and chiral matter, outlining a simple strategy for producing circularly polarized lasing from chiral metal-organic frameworks (MOFs), such as the zeolitic imidazolate framework (ZIF), embedded with achiral laser dyes (L/D-ZIF⊃dyes). It is found that the stimulated emission threshold and intensity are influenced by the interplay between the chiral polarization of the pump light and the inherent chirality of the MOF nanoparticles. We further present the design of a chiral vertical-cavity surface-emitting laser (VCSEL), comprising an L/D-ZIF⊃dyes solid-state film sandwiched between a high-reflectivity distributed Bragg reflector (DBR) mirror and a silver film. The cavity-based lasing exhibits higher asymmetry between emitting left-handed and right-handed polarized light compared to chiral spontaneous emission (SE) and amplified spontaneous emission (ASE), with an asymmetry value glum of approximately ±0.31. This value is nearly four-fold greater than that of SE and twice that of ASE. Our findings reveal a new approach to amplify chiral signals, promoting the comprehension and application of chiral–matter interactions, and offering a simple yet effective strategy to fabricate chiral lasers.

Dynamic modulation of microcavity lasers is crucial for achieving stable single-mode operation with high monochromaticity, compact footprint, and directional emission. However, the emergence of higher-order transverse modes with increasing cavity dimensions has frustrated efforts to scale up cavities while maintaining stable single-mode operation. To date, no suitable physical mechanism has been identified that enables cavity size-independent single-mode lasing. Herein, a breakthrough non-invasive technique is developed for in situ engineering of natural nano-grooves in large-size ( ≥ $ \ge $ 20 × 20 µm) perovskite microplates (MPs) through kinetically controlled vapor-phase epitaxy, achieving unprecedentedly precise mode control for optimal single-mode lasing performance. Critically, these well-defined grooves can alter the lasing resonance modes within the microlasers, enabling the transition from whispering gallery mode (WGM) to Fabry-Pérot (F-P) mode. The optical anisotropy induced by engineered groove structures also achieves polarized lasing emission with a high degree of polarization approaching 0.65. Additionally, numerical simulations elucidate that the external-cavity-free, high-quality (≈2660), and single-mode F-P lasing behavior under large-size conditions arises from the coupling of multiple cleavage cavities, which is induced by broken grooves in perovskite MPs morphology. This study pioneers a mode-selective modulation approach that enables scalable polarization engineering in large-area single-mode microlasers, fundamentally advancing multifunctional integration in photonics and high-density optoelectronic systems.
