The organisation of the 2025 European Conference on Integrated Optics edition is in hands of Cardiff University.

The conference focuses on leading edge research on integrated optics, optoelectronics and nano-photonics and gathers experts from academia and industry to show their latest technical results, and showcase their products and services. The application scope is broad and it ranges from tele/datacom communications, optical interconnects, and (bio) optical sensing applications to more disruptive areas as quantum computing and mid-IR photonics.
