Abstract
The THz-emission due to the field-driven dynamics of photoexcited carriers in semiconductor superlattices was investigated for the combined action of static and alternating fields. The applied field was written as F(t) = F0+F1 cos(ω-L$/t). For such a driving field, it was shown within a simple model, that the equations governing the intraband dynamics in the field-driven superlattice should be analogous to the ones describing the superconducting Josephson junction. The transport properties in this regime can be described by the picture of multi-photon assisted tunneling between Wannier-Stark states.
