Advanced semiconductor lasers for high-speed data communication — •Johann Peter Reithmaier — Institute for Nanostructure Technologies and Analytics (INA), CINSaT, University of Kassel, Germany

An overview will be given on advanced semiconductor lasers and related optoelectronic devices, which are mainly utilizing specific properties of low-dimensional electronic systems, such as quantum dots (QDs) or mixed multi-dimensional systems. The special focus will be on laser properties, which are of highly interest for high-speed optical data communication. In particular, examples will be discussed for high-speed direct modulation, ultra-narrow linewidth lasers for coherent communication and high-speed high-temperature operation of semiconductor optical amplifiers. The tutorial will also give some background for the understanding of the more recent obtained record values of QD lasers in temperature stability, nearly-zero linewidth-enhancement factors and emission linewidths below 30 kHz at room temperature.
