Abstract :
We combined two different time resolved measurements to determine the excitonic capture path in electrically pumped InGaAs/GaAs quantum dots (QDs) in-a-well (DWELL). The QDs form the active medium of a Semiconductor Optical Amplifier (SOA), a waveguide based electrically pumped device designed to amplify light around 1.3 μm.
