Dutch Photonics Event 2026
by haffert＠strw.leidenuniv.nl 04 Feb '26

04 Feb '26

Hi all, This might be an interesting event for some of you. I am most likely going to go there. Let me know if you are interested. Best Sebastiaan Dear researchers in optics and photonics, We would like to draw your attention to the DutchPhotonicsEvent ( <https://dutchphotonicsevent.nl/> https://dutchphotonicsevent.nl/) which will be held in the ‘Brabanthallen' venue in ’s Hertogenbosch on September 16 and 17, 2026. The DutchPhotonicsEvent, organized by PhotonicsNL, has a long-standing tradition bringing together industry and academics in the Netherlands. This coming iteration, it will be significantly renewed and expanded to include a two-day scientific conference with three parallel sessions, plenary sessions, a poster session, a job fair, and an exhibit. The ambition is to bring together the national science and industry communities across the entire fields of optics and photonics in The Netherlands. Currently confirmed plenary speakers include Andrea Alù (CUNY, USA) and Christine Silberhorn (Paderborn University, Germany). We hope you and your colleagues will join us for this exciting meeting! We warmly welcome researchers from all levels to submit abstracts for contributed talks or posters. The deadline for abstract submission is March 15. Abstracts should be at maximum 250 words and can contain an optional figure. See the <https://dutchphotonicsevent.nl/submission/> abstract submission website <https://dutchphotonicsevent.nl/submission/> for details. We invite contributions from all areas within optics and photonics and adjacent fields, including these directions (among others): * Integrated photonics * Nonlinear optics * Statistical optics * Quantum optics * Nanophotonics and metasurfaces * Optical fibers * Photonic and photovoltaic materials * Lasers, light sources and detectors * Ultrafast science and applications * Optical communications * Optical sensing and metrology * Neuromorphic photonics * Quantum communication, sensing and computing * Microscopy and computational imaging * Optics in advanced instrumentation We rely on your help and participation to make this initiative a success. Please help us spread the word by forwarding this email to your team members and interested students and colleagues. We hope to see you in Den Bosch in September! Best regards, on behalf of all organizers, Organizing Committee, DutchPhotonicsEvent Petra Wicherink (PhotonicsNL) Andrea Fiore (Eindhoven University of Technology) Anke Peters (Optics Netherlands) Wilbert IJzerman (Signify) Daniela Godoy (PhotonicsNL) Scientific Committee, DutchPhotonicsEvent Ewold Verhagen (AMOLF, chair) Imran Avci (VU Amsterdam) Stefan Bäumer (TNO) Michiel de Dood (Leiden University) Johannes Hohlbein (Wageningen University) Maria Antonietta Loi (Groningen University) David Marpaung (Twente University) Allard Mosk (Utrecht University) Chigo Okonkwo (Eindhoven University of Technology) Silvania Pereira (Delft University of Technology) Jessica Steinlechner (Maastricht University)

Hi all, I am organizing a meeting next week on Tuesday (Jan 20th) where the research group from Delft that works on space technologies will visit us. We will visit them on a different date to see what they are doing. I am proposing this as a tentative schedule: Proposed schedule for Science and Technology group visit at Leiden Time What Where 9:45 – 10:15 Walk-in + coffee Kaiser Lounge 10:15 – 10:45 Welcome by Sebastiaan + overview presentation of what we do. 11:00 – 11:45 METIS integration hall visit METIS integration hall 11:45 – 13:15 Lunch UFO, The dish 13:15 – 14:00 2x Leiden Presentations + Q/A TBD 14:00 – 14:30 Optical Lab visit 14:30 – 15:15 2x Leiden Presentations + Q/A TBD 15:15 – 15:45 Coffee Break 15:45 – 16:30 2x Leiden Presentations + Q/A TBD 16:30 – 17:15 Discussion about synergies TBD 17:15 – 20:00 Dinner in Leiden Does anyone have any comments or suggestions about the schedule? I was thinking of maybe adding a visit to SRON in, but then we don’t have that much time to discuss the research side.
