Project Description

The project expands the SESAM modelocking approach  to a new class of semiconductor lasers with wafer-scale integration of both the gain and the absorber into a vertical emitting  structure.  The goal is to scale both power and pulse duration to new regimes that enable for example stable frequency comb generation.
