ECOC 2025
Symposia
Green ICT
Monday, 29th September 2025 13:30-17:00
Join this symposium to hear about what’s done to evaluate ICT’s climate footprint – and what’s missing to get a generally useful tool to assess ICT services. How accurately can we determine the CO2 footprint of ICT, in general and in specific cases, and how can we use this to estimate whether ICT is good or bad for the climate, or which ICT service is more climate friendly.
- We will learn about life cycle analyses of communication technologies used to derive the CO2-footprint of e.g. submarine cables and terrestrial networks.
- We will learn what network operators do to become more sustainable.
- We will learn how current knowledge of CO2-footprint is used to evaluate ICT-services such as streaming.
- We will learn about the total ICT footprint for various countries, and globally.
- We will learn about how much ICT saves in CO2 in other sectors, compared to its own footprint.
There will be presentations from the various key organisations in this domain, describing their efforts and targets, and there will be a panel discussion on what may be missing, aiming at ending up with a brief statement, detailing the recommendations for steps ahead and evaluations of current standings.
Organisers: Leif Oxenloewe and the GreenCOM project
100 years of Bell Labs
Tuesday, 30th September 2025 13:30-17:00, in Auditorium 15
Join us for an exclusive, in-depth workshop to celebrate a century of world-changing innovations sparked by Bell Labs. This special three-hour event, split into two engaging sessions, will take you on a journey through the history and future of optical communications.
- The Origin of a Game-Changing Technology (60 minutes)
Hear from Sir David Payne from University of Southampton, Emmanuel Desurvire and R. Giles of Bell Labs— as they recount the thrilling origins of the Erbium-Doped Fiber Amplifier (EDFA).
- Bell Labs Alumni: Reflections on the ingredients of breakthrough innovations (90 minutes)
The second segment gathers ten distinguished Bell Labs alumni to share personal reflections on influential scientific papers they authored or co-authored.
- Student Pitch Competition: The Bell Labs Centennial Prize (30 minutes)
In the concluding half-hour, future innovators take center stage in a fast-paced, three-minute pitch competition aimed at redefining what’s possible in optical communications.
Organisers: S. Bigo, René-Jean Essiambre, Jean-Paul Hamaide, Jelena Pesic
Celebrating Nobel Prize in Physics - merging machine learning and photonics
Wednesday, 1st October 2025 14:00-17:30, in Auditorium 15
Join us for a special symposium bringing together leading experts to celebrate the 2024 Nobel Prize in Physics and explore the powerful intersections of machine learning and photonics.
From quantum and optical communication systems to nonlinear fibre optics, photonic computing, and machine learning–aided signal processing, the symposium highlights new insights, experiments, and approaches at the crossroads of light, information, and intelligence.
