It is a great pleasure to welcome you to the 28th International Semiconductor Laser Conference (ISLC), which will take place in Matsue Japan.  The ISLC has the tradition of more than 50 years, running single session format, providing an opportunity to all participants with fruitful discussions not only during the sessions but also during the conference periods. October in Japan is a good season to enjoy the beautiful scenery and food. We hope you enjoy the beautiful and historical city of Matsue.
