## Description

- description: 'Laser devices produced through solution-processed perovskite quantum
    dots (QDs) offer broad spectral tunability as well as ease of fabrication. Utilizing
    quasi-BIC modes, solution-processed QD laser devices have been demonstrated with
    a nanostructure coated in a thin-film gain media configuration. However, light
    leakage through thin-film guiding from the cavity side edges becomes more pronounced
    when shrinking the cavity size, posing challenges for the miniaturization of quasi-BIC-based
    lasers. Here, the fabrication of well-defined patterns of QDs via a solution process
    allows us to take advantage of the pattern edges to reduce losses through the
    cavity edges. We report a single-mode BIC laser by using CsPbBr3 QDs with a narrow
    linewidth below 0.1 nm. Importantly, we realize a miniaturized quasi-BIC laser
    with a size as small as 10×10 μm², making it the smallest among existing solution-processed
    BIC lasers. This work provides a strategy for developing ultra-compact BIC lasers
    via solution-processed gain media. '
