World of Photonics Congress 2025

The event in Europe will be supplemented by three trade fairs: Laser World of Photonics, World of Quantum and automatica.

The World of Photonics Congress 2025 will comprise five conferences with more than 3,000 scientific presentations and poster sessions. It will cover the entire range of topics from basic research to practice-oriented developments and industrial applications.

“Leading international researchers in the field of photonics meet here to share knowledge, discuss new trends and network,” said Anke Odouli, Exhibition Director. “The World of Photonics Congress not only brings together the brightest minds in the industry, but also shows how closely science and industry work together when it comes to light as a driver of innovation.”

This year, two Nobel laureates in physics will be guests at the congress and give plenary talks at the CLEO / Europe—EQEC 2025 conference. Ferenc Krausz will talk about sub-atomic motions and their potential for science, technology and medicine (EQEC plenary talk and award ceremony, 24th June, 10:30 to 12:30, Room 1). Anne L’Huillier will give a talk on attosecond light pulses for the study of electron dynamics (CLEO / Europe plenary talk, 25hth June, 14:00 to 15:30, Room 1).

The World of Photonics Congress covers all research disciplines in the field of photonics. It brings together five individual conferences backed by scientific societies and research institutes in photonics. The plenary session will be held on 24th June from 8:30 to 10:00. Christine Silberhorn will talk about the scaling of photonic systems for quantum information processing.

The details on the individual conferences and their respective plenary speakers are as follows:

• CLEO / Europe—EQEC 2025 is Europe’s largest conference for photonics and related fields of research. CLEO / Europe presents the latest developments in a broad spectrum of laser and photonics areas, while EQEC covers the basics of quantum optics. The program comprises presentations, tutorials, poster sessions and short courses. CLEO / Europe—EQEC 2025 is organised by the European Physical Society (EPS), Optica and the IEEE Photonics Society
• LiM—Lasers in Manufacturing is concerned with the field of laser material processing. The three sub-conferences will be dedicated to the areas of macro applications, nano and micro applications and additive manufacturing. The organiser is the Scientific Society for Laser Technology and Photonics. In this year’s plenary talk, Chu Lun Alex Leung and Barbara Previtali will uncover process and defect dynamics during additive manufacturing with X-ray vision and present innovative beam shaping solutions for e-mobility (23rd June, 10:30 to 12:30, Room 13b).
• The trends and perspectives of digital optical technologies will be the focus of the conference of the same name, which is organised by SPIE Europe. Digital optical technologies reflect the trends of the latest technologies, such as 3D sensors, immersive multimedia, new types of displays, light sources and imaging systems. Plenary speaker Aydogan Ozcan will discuss programming light diffraction for information processing and computational imaging (23rd June, 9:00 to 10:00, Room 21).
• The Optical Metrology conference, also organised by SPIE Europe, will explore the latest research findings about measuring systems, videometrics and inspection. The focus will be a wide range of applications from industrial use and vehicle navigation to archeology, architecture and art. In a plenary talk, Wolfgang Osten and Alberto Diaspro will address the wide scale range of optical measurement technology and its exploration as well as the intelligent microscope on the nanoscale (23rd June, 16:00 to 17:30, Room 1).
• The European Conferences on Biomedical Optics (ECBO) is focused on optical and biophotonic technologies for diagnostics and therapeutics. The plenary talk by Kishan Dholakia and Irene Georgakoudi will deal with optical frontiers in reproductive health and label-free two-photon microscopy for dynamic imaging of cellular metabolism and matrix remodeling in living tissues (23rd June 23, 10:30 to 12:30, Room 5). The conference is organizsed by SPIE and Optica.

In addition to the conferences, special events such as lectures, discussions and mentoring programs promote international exchange as well as raise awareness of topics such as diversity, equality and integration in the photonics industry.
