Proceedings of the 26th European Conference on Integrated Optics

This book presents peer-reviewed and selected papers from the 2025 European Conference on Integrated Optics (ECIO), held on June 10–12, 2025, and organized by Cardiff University, UK, in collaboration with University of York, UK. In the 25th edition of this conference, internationally recognized experts share their latest research and showcase their products and services in the field of integrated optics, optoelectronics, and nano-photonics. The conference focuses on leading-edge research and its broad application scope ranges from tele/datacom, optical interconnects, and (bio) optical sensing to more disruptive areas such as quantum computing and programmable photonics.
