摘要
We demonstrate the external control of the intersubband polariton coupling in a GaAs/AlGaAs microcavity, utilizing the electronic tunneling between energetically aligned ground states of an asymmetric coupled quantum well structure. We suggest this scheme as the basic element for the ultrafast manipulation of the polariton ground state. Preliminary results of intersubband polaritons in InAs-AlSb microcavities, towards the realization of the ultra-strong coupling regime, are also reported.
