The European Conference on Integrated Optics ECIO 2017 is at the Auditorium of the Technical University of Eindhoven. The conference scope extends from new enabling materials to the design and modelling of photonic structures, functions, devices and circuits. We also capture innovations in hybrid integration, system-on-chip and system-in-package integration. Application areas range from optical tele- and data communications; optical interconnects, switching and storage; data and information processing, including integrated quantum circuits; and optical monitoring and sensing, including mid-IR photonics.
