Workshop: Vertical Cavity Lasers

On May 20th 2016 the IEEE Photonics Society Sweden Chapter and the Fibre Optic Communications Research Centre (FORCE) at Chalmers invites to a workshop on Vertical Cavity Lasers with IEEE Distinguished Lecturer Professor Eli Kapon from the Swiss Federal Institute of Technology (EPFL) in Lausanne, Switzerland.

The vertical cavity surface emitting laser (VCSEL) is a light source produced in large volumes for data communication, sensing, optical pumping, infrared illumination and industrial heating. Research on VCSELs enable steadily improving performance, new innovative VCSEL designs, VCSELs in new material systems to expand the range of wavelengths and applications, and light source integration for siliconbased photonic integrated circuits. The workshop will shed light on some of these developments.

The workshop is held in the lecture hall Kollektorn at the Department of Microtechnology and Nanoscience at Chalmers University of Technology with address Kemivägen 9. Directions

The workshop, including lunch and coffee, is free of charge. Register no later than May 6 by sending an email to Anders Larsson at:
