We investigate the dephasing dynamics in semiconductor superlattices using timeresolved four-wave mixing. The signals show a periodic modulation which can be related to Bloch oscillations in the superlattice miniband. The oscillation frequency is strongly dependent on the applied field, in agreement
The optical nonlinearity and bistability (OB) induced by intersubband transitions (ISBTs) in semiconductor superlattices are studied by means of the Kronig-Penney model and the density-matrix method. The OB state equation in a Fabry-Perot configuration is derived. It is shown that the ISBT-induced O
