The ISLC is dedicated to latest developments in semiconductor lasers, amplifiers and LEDs. The conference seeks to be as inclusive as possible, to represent excellence from all global regions and in all areas of currently active semiconductor laser research. ISLC 2021 and the associated exhibition are organized by the Ferdinand-Braun-Institut, Berlin and supported by IEEE Photonics Society as technical sponsor.

The conference provides many fine confirmed laser legend, plenary and invited speakers as well as dedicated Sunday workshops on highly relevant topics. The conference is accompanied by a focused exhibition.

More about the ISLC

The ISLC has more than 50 years of tradition, attended by a highly international audience and with locations cycling between the Americas, Asia/Australia and Europe/Mid-East/Africa regions every two years. Since its founding, many new and ground-breaking semiconductor devices have been first presented at this prestigious conference. The ISLC was last in Germany in 2002.

Topics include:

  • semiconductor optical amplifiers
  • silicon compatible lasers
  • VCSELs
  • photonic band-gap and microcavity lasers
  • grating controlled lasers
  • multi-segment and ring lasers
  • quantum cascade and interband, sub-wavelength scale nanolasers
  • mid IR and THz sources
  • InP, GaAs and Sb materials
  • quantum dot lasers
  • high power and high-brightness lasers
  • GaN and ZnSe based UV to visible LEDs
  • communications lasers
  • semiconductor integrated optoelectronics                           

We very much look forward to welcoming you to the 27th ISLC in October 2021!
