The European Conference on Integrated Optics (ECIO) is the largest dedicated event on integrated optics in Europe and longest-running event dedicated to cutting-edge research and technological development in integrated photonics and nanophotonics.
It covers topics spanning from advanced materials and technologies to novel device concepts and emerging applications.

ECIO has now reached its 25th edition!

Join us in Aachen for a full in presence ECIO edition !

The conference focuses on leading edge research on integrated optics, opto-electronics and nanophotonics. The meeting gathers experts from academia and industry to show their latest scientific and technical results, and to showcase their products and services. The application scope is broad: it ranges from telecom / datacom to optical imaging, sensing, metrology, up to more disruptive areas like quantum and neuromorphic computing.

The most recent advances in the wide-ranging field of photonic devices are among the main features of the conference. Conference topics cover waveguide theory and novel waveguide concepts; devices, photonic integrated circuits (PICs) and their applications; technology platforms and materials, such as silicon-based photonics and III-V optoelectronics; circuit design models and tools; assembly, packaging and testing; PIC exploitation in classical and emerging applications.
