Welcome to the Website of the
11th European VCSEL Day 2018 Workshop
in Ulm on April 12−13

The vertical-cavity surface-emitting laser (VCSEL) business is booming more than ever. A record number of devices is being produced worldwide for traditional and young market segments. Time-of-flight sensing for gesture recognition and infrared illumination for 3-D imaging in smartphones are prominent examples. The 11th VCSEL Day will provide a European forum to discuss the state of the art and present latest research results: novel device concepts, performance records, inexplicable effects, new application ideas – contributions on all VCSEL-related topics are most welcome!

VCSEL Day 2018 features

  • Technical sessions with 50 % presentation time and 50 % discussion, e.g., 10 min + 10 min (in contrast to conferences with usual ratios of 12-to-3 or 15-to-5)
  • Should discussions be “slow”, doors will be locked, the WLAN network will be shut down, and a Faraday cage will be activated.
  • The presentations will not be collected or distributed. No audio or video recordings will be made. We will vote if photos may be taken during the sessions or not. All secrets can safely be shared.
  • Printed and electronic copies of the workshop proceedings with the one-page abstracts will be provided.
  • A poster session preceded by one-minute teaser presentations will be scheduled should oral presentation slots be filled.
  • In case of a VCSEL Day run, a limit might be set on the number of participants. Preference will be given to (a) a variety of presented topics and (b) a variety of attending groups and organizations.
  • No workshop fee
  • Catering, social: three coffee breaks, on-site lunch on Thursday, dinner in the city center of Ulm sponsored by Philips Photonics, light lunch after the closing on Friday
