Terahertz Bloch oscillator with a modulated bias
Timo Hyart, Natalia V. Alexeeva, Jussi Mattas +1
Electrons performing Bloch oscillations in an energy band of a dc-biased superlattice in the presence of weak dissipation can potentially generate THz fields at room temperature. T…

Nondegenerate parametric amplification in superlattice and the limits of strong and weak dissipation
Timo Hyart, Kirill N. Alekseev
We develop a semiclassical theory of the nondegenerate parametric amplification in a single miniband of superlattice. We present the formulas describing absorption and gain of sign…

Theoretical backgrounds of nonlinear THz spectroscopy of semiconductor superlattices
Alexey V. Shorokhov, Kirill N. Alekseev
We consider terahertz absorption and gain in a single miniband of semiconductor superlattice subject to a bichromatic electric field in the most general case of commensurate freque…
