摘要：

圆偏振发光(CPL)在量子计算、3D显示和生物成像等领域具有重要应用价值，但其实际应用面临不对称因子低、发光亮度低、方向性差和发射谱宽等挑战。为解决这些问题，圆偏振激光技术通过受激辐射放大和谐振腔模式选择，可显著提升CPL性能，实现高g值(接近理论极限2)、高亮度、窄线宽和强方向性的圆偏振光输出。目前，有机微晶、钙钛矿等材料虽能实现高g值圆偏振激光，但仍存在制备复杂、生物相容性差等问题。相比之下，碳点(CDs)因其制备简单、成本低、毒性小、易修饰和生物相容性好等优势，成为极具潜力的新型圆偏振增益介质。本文系统综述了圆偏振激光的材料体系、器件类型及应用进展，重点探讨了CDs作为增益介质的优势及其在3D显示、光学通信、信息加密和生物传感等领域的潜力，并展望了CDs圆偏振激光的未来发展方向和挑战，为推动高性能圆偏振激光器件的实用化进程提供了参考。

Abstract:

Circularly polarized luminescence (CPL) has significant application value in fields such as quantum computing, three-dimensional (3D) display, and bioimaging. However, its practical application faces challenges including low dissymmetry factor (g), insufficient quantum yield, poor directionality, and broad emission spectrum. To address these issues, circularly polarized laser technology can significantly enhance CPL performance through stimulated emission amplification and resonant cavity mode selection, achieving circularly polarized light output with high g (close to the theoretical limit of 2), high brightness, narrow linewidth, and strong directionality. Currently, although materials like organic microcrystals and perovskites can realize circularly polarized laser with high g, they still have problems such as complex preparation and poor biocompatibility. In contrast, carbon dots (CDs) have emerged as a highly promising new type of circularly polarized gain medium due to their advantages of simple preparation, low cost, low toxicity, easy modification, and good biocompatibility. This paper systematically reviews the material systems, device types, and application progress of circularly polarized laser, focusing on the advantages of CDs as gain media and their potential in fields such as 3D display, optical communication, information encryption, and biosensing. It also prospects the future development directions and challenges of CDs-based circularly polarized lasers, providing a reference for promoting the practical application process of high-performance circularly polarized laser devices.
