It is a great pleasure to welcome you to the 27^th International Semiconductor Laser Conference (ISLC), which will take place in Potsdam.  Potsdam is one of Germany's most beautiful cities and only a short distance away from the capital Berlin. It has played a key role in German, European and world history, which is visible throughout the city.

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.

We warmly encourage you to attend ISLC 2021 and to submit your most recent research results. We also wish you an enjoyable stay in the beautiful historical city of Potsdam.
