The purpose of EOS is to contribute to progress in optics and photonics and to promote their applications at the European and international levels.

The EOS was founded on 24 May 1991. The purpose of the society is to contribute to progress in optics and related sciences, and to promote their applications at the European and international levels, by bringing together individuals and legal entities involved in these disciplines and their applications. The European Optical Society (EOS) serves as the joint forum for all individuals, companies, organisations, educational institutions, and learned and professional societies, who recognise the opportunity and challenge that a common European base provides for the development of optics in its broadest sense.

📰 JEOS-RP Editor’s Pick 📰

The Journal of the European Optical Society – Rapid Publications (JEOS-RP) is an open-access platform covering a wide range of research in optics and photonics. Each month, the Editor-in-Chief highlights an exceptional piece of work.

We’re excited to share the latest Editor’s Pick: "Directional light redirection from a buried femtosecond-laser-written tilted-plane array in fused silica"

📖 Authors: Jonas Kuhl, Ingo Lebershausen, Jens-Uwe Just, Ulrich H. P. Fischer and Stefan Kontermann
🔗 Read the full article here: J. Eur. Opt. Society - Rapid Publ. 2026, 22, 66 👉 https://doi.org/10.1051/jeos/2026058

The authors report on three laterally separated buried tilted-plane redirection arrays fabricated at different pulse energies by femtosecond direct laser writing in a single fused-silica substrate. Using the setup shown in Figure 3 of the paper, the authors have quantified the effective captured redirection coefficient for an individual tilted plane in the present camera-lens collection geometry, which increased significantly with a minimal increment in pulse energy. The results show process-level tunability, but the steep pulse-energy dependence also presents a challenge for fabrication tolerance and reproducibility.

📷:
Top figure (Figure 1): Multiscale schematic of the buried tilted-plane arrays and writing geometry. (a) The 25 mm × 50 mm × 5 mm fused-silica substrate contains three laterally separated arrays fabricated at Ep = 75 nJ, 77 nJ, 80 nJ and positioned at the nominal coordinate z = −1 mm. (b) Each 1 mm × 2 mm array comprises 40 tilted planes arranged as four columns and ten rows. Dashed boxes identify the regions enlarged in the following panels. (c) Each individual plane has a projected footprint of 250 μm × 200 μm and is tilted by 45°. Parallel tracks are scanned along v with the writing polarisation E orthogonal to the scan direction, while the writing beam propagates along −z. Only every tenth track is shown for clarity; the actual functional track pitch is Λ = 0.5 μm. Panels are not drawn to a common scale.

Middle figure (Figure 3): Acquisition setups for measuring redirected light from the tilted planes: (a) He–Ne illumination with camera imaging (collection toward +n̂ and −n̂ by sample reorientation; the fixed camera-lens geometry defines the reported captured powers), (b) unpolarised white-light illumination with a scanning optical fibre probe (collection toward +n̂ only).

Bottom figure (Figure 4): Redirected signals measured from three laterally separated arrays fabricated in the same substrate using identical acquisition parameters within each measurement setup. Top row: signal captured with the camera under He–Ne laser illumination. Bottom row: signal captured with the optical fibre under white-light illumination. The pulse energies for the respective columns are Ep = 75 nJ, 77 nJ, 80 nJ.

At the Closing Ceremony of EOSAM 2026, we were thrilled to announce where the EOS community will gather next.

EOSAM 2027 is heading to Wrocław, Poland, taking place 27–30 September 2027, organized by EOS in close collaboration with Wrocław University of Science and Technology.

Thank you again to everyone who made EOSAM 2026 in Tampere such a special week, one where we celebrated 35 years of EOS and 20 years of EOSAM together. We can't wait to continue the story in Wrocław.

More information, including venue, key dates, and the call for papers, is coming soon, keep an eye on our website: https://www.europeanoptics.org/events/eos/eosam-2027.html

Mark your calendars, see you there! 🇵🇱

Continuing our highlights! Rounding out our thank-yous, there are a few more groups we would like to mention.

None of this would have been possible without the generous support of our sponsors: Gold Sponsor AeroDIODE, and Silver Sponsors Thorlabs, Finnish SpecialGlass, Zurich Instruments, and Light Conversion, along with American Elements, RhySearch, Evatec, and ICO. A big thank you as well to all 23 companies who exhibited with us this year and helped make the exhibition floor such a lively part of the week.

We would also like to thank our EOS national societies and partners for their continued support and contribution to the EOS community.

A huge thank you to everyone who contributed to making such a memorable week!

Continuing our highlights! There’s one group of people this whole week simply wouldn’t have happened without.

EOSAM 2026 was organized by EOS in close collaboration with Tampere University, Photonics Finland, and the PREIN Flagship, whose support made this week possible from the very start.

Behind the scenes, EOSAM 2026 was brought to life by General Chairs Goëry Genty and Juha Toivonen (Tampere University), Programme Chairs Jyrki Saarinen (University of Eastern Finland) and Ignacio Moreno (Universidad Miguel Hernández, EOS President), and the EOS Office, led by Elina Koistinen, together with Boglárka Selényi and Tiina Romppanen. They worked together with the local team at Tampere University, Kristiina Pispala and Tea Vellamo; the Photonics Finland team, Tuukka Pakarinen and Anne-Maria Kankaisto; and EOS Treasurer Roelene Botha, who coordinated the student prizes.

Many others also played an essential role, including the chairs of our eight Topical Meetings and five Focused Sessions, the session chairs who kept every room running on time, and the programme committee members who reviewed submissions and helped shape the scientific programme long before the week began.

To everyone who gave their time, energy and expertise to make EOSAM 2026 happen, thank you. We couldn't have done it without you!
