摘要

金属卤化物包晶是一种优秀的直接带隙半导体材料，可为激光和放大器应用提供高光学增益。通过使用环形布拉格空腔来实现包光体中的光-物质相互作用，为高性能片上光子源带来了巨大前景。在此，我们报告了我们开发的一种用于包晶有源光子学的无蚀刻制造方法，并在准二维 Dion-Jacobson-phase 包晶中进行了环形布拉格激光器的实验演示。所演示的包晶体激光器性能卓越，包括 8 μJ/cm2 的低激光阈值和 1.2 × 104 的创纪录高品质因数。由于采用了 Dion-Jacobson-phase perovskite 和材料兼容的制造工艺，这些激光设备具有出色的稳定性。这项工作为大面积、单模表面发射的包晶体激光器开辟了一条新途径，同时也为包晶体集成光子学提供了一个新平台。

Etchless Dion–Jacobson-Phase Perovskite Surface-Emitting Circular Bragg Lasers with an Ultrahigh Q Factor

Metal halide perovskites are an excellent direct-bandgap semiconductor material that can possess high optical gain for laser and amplifier applications. Engineering light–matter interactions in perovskites by using a circular Bragg cavity holds great promise for high-performance on-chip photonic sources. Here, we report our development of an etchless fabrication method for perovskite active photonics with an experimental demonstration of circular Bragg lasers in quasi-2D Dion–Jacobson-phase perovskites. The demonstrated perovskite lasers exhibit excellent performance including a low lasing threshold of 8 μJ/cm² and a record-high quality factor of ∼1.2 × 10⁴. These laser devices have excellent stability due to the adoption of the Dion–Jacobson-phase perovskite and material-compatible fabrication processing. This work opens a new avenue to large-area, single-mode surface-emitting perovskite lasers and also provides a new platform for perovskite integrated photonics.
