The“Belt-and-Road” & “BRICS” Forum for Advanced Photonics was initiated in 2019 by College of Optical Science and Engineering (COSE) of Zhejiang University (ZJU), China. The event aims to bring together experts, scholars, and researchers in the field of photonics to discuss and exchange ideas on the latest advancements in this rapidly evolving domain. The forum will provide a platform for participants to share their cutting-edge research findings, engage in interdisciplinary discussions, and foster collaborations among researchers and practitioners, specifically from "B&R" and "BRICS" countries.
