Abstract
We present a microscopic analysis of coherent effects induced by elect ric fields in photoexcited semiconductors in the presence of the Coulo mb interaction. Both the terahertz emission and four-wave-mixing signa ls arising from Bloch oscillations in a semiconductor superlattice are computed consistently. It is predicted that Bloch oscillations should be observable also for miniband widths on the order of the exciton bi nding energy.
