In cutting-edge domains like high-precision sensing, quantum information processing, and optical micro-manipulation, there's an urgent demand for a pivotal optical phenomenon—chiral vortex light. This unique form of light possesses a distinct rotational direction, distinguishing it from its mirror image and enabling specific interactions with chiral substances, such as proteins. Its significance lies in its ability to facilitate high-sensitivity detection, precise quantum state manipulation, and light-induced rotation. Nevertheless, conventional approaches to generating chiral lasers have hinged on intricate spiral resonators, chiral liquid crystal materials, or asymmetric optical pumping techniques. These methods are not only challenging to fabricate but also suffer from low integration levels. Moreover, the chirality they produce is predominantly derived from external perturbations, posing challenges in ensuring stability and mode purity.

Recently, a collaborative research team, spearheaded by Professor Peng Chao from Peking University's School of Electronics, in conjunction with Academician Zheng Wanhua's team from the Semiconductor Institute of the Chinese Academy of Sciences and a research group from the Australian National University, has achieved notable advancements in this field.
