Abstract

Self-sustained pulsations in the output power of metal-organic chemical vapor deposition grown ridge-waveguide lasers with InGaAs quantum dot active region are reported. The characteristics of the output power pulsations range, frequency, and modulation depth are presented. The origin of the pulsations is explained in terms of the properties of the quantum dot active region.
