The International Conference on Nonlinear Optics and Excitation Kinetics in Semiconductors (NOEKS) will be the 15th meeting in a series with the outstanding tradition of bringing together leading scientists in the field of semiconductor optics. NOEKS 15 follows this tradition by covering the most recent developments in this rapidly evolving field, which involve advanced and new materials, novel experimental techniques, and recent theoretical progress. There will be no parallel sessions and the conference will provide plenty of opportunities for discussions.
