Abstract
We investigate the dephasing dynamics of Bloch oscillations in semiconductor superlattices by transient spectrally resolved four-wave mixing. The dephasing phenomena are studied under various carrier densities, lattice temperatures, and excitation conditions. In particular, we show that the decay can be strongly influenced by interference due to the excitonic effects on the Wannier-Stark ladder.
