Abstract
We observe carrier transfer between self-assembled InGaAs/GaAs quantum dots (QDs) at temperatures above 230 K using differential transmission spectroscopy (DTS). The sample is a single layer of QDs embedded in a semiconductor waveguide to increase the interaction length of the weakly absorbing QDs. Pump and probe light is generated by an optical parametric oscillator synchronously pumped by a mode-locked Ti:sapphire laser. The probe signal is isolated from the pump by high frequency modulation and detection with an RF lockin amplifier.Proceedings Title
