Abstract
Steady-state and picosecond photoluminescence experiments on CdTe/CdZn Te and CdTe/CdMnTe asymmetric double quantum wells are presented. An e xternal magnetic field is used to tune the coupling between the two QW s by allowing resonances to occur between excitonic states. Very effic ient tunnelling is found when an exciton from the high-energy QW can t ransfer either with the emission of an LO phonon or via the resonance with the 2s state of the low-energy QW.
