Ultrafast electric field induced nonlinear response in ZnSe/ZnSeS superlattices

Abstract:
We report the observation of an ultrafast optical nonlinearity in ZnSe/ZnSeS superlattices which arises from the generation of an internal field due to charge separation caused by preferential hole trapping. The absorption recovery is extremely fast, similar to 650 fs, being due to the subsequent localisation of electrons.
