Abstract
We report enhanced electroabsorption in selectively doped (Ga,In)As/(Al,In)As Asymmetric Double Quantum Wells (ADQWs) by the use of real space electron transfer. The electron concentration in both the wide and narrow wells is investigated by field dependent absorption and photoluminescence spectroscopy. Additionally, a study of carrier dynamics in these ADQW structures indicates that electrons tunnel between the coupled wells on picosecond time-scales.
