The International Semiconductor Laser Conference has a long tradition as the leading international conference where researchers and engineers from all over the world meet to share and discuss the latest developments in semiconductor lasers, amplifiers and LEDs. The 25th International Semiconductor Laser Conference will be held in Kobe Japan from 12- 15 September 2016. The conference will include both oral and poster sessions of contributed and invited papers, as well as a plenary session comprising reviews on a number of important and timely topics. A rump session will feature special topics of current interest for discussion in a more relaxed and open atmosphere. In addition, attendees will be able to participate in workshops on current hot topics during the first day of the conference. Technical results on all aspects of semiconductor lasers, amplifiers, LEDs and integrated devices, from basic physics of new materials and structures to new and improved device concepts are covered.
