Ultrafast electric field induced nonlinear response in ZnSe/ZnSeS superlattices
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, ∼ 650 fs, being due to the subsequent localisatio...

| description | 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, ∼ 650 fs, being due to the subsequent localisation of electrons. |
