The nonlinear high-frequency conductance of superlattices due to the nonparabolicity of minizones has been investigated. Exact expressions for the current excited with a harmonic electric field are obtained. A selftransparence effect is predicted. It is shown that in the presence of a strong high-frequency field the increase of the low-frequency oscillations is possible. The frequency doubling and the high-frequency signal detection in the presence of a strong constant electric field is also investigated.

TL;DR: In this article, a multiscale simulation of solid-state high-order-harmonic generation was performed for dielectrics and it was shown that mesoscopic effects of the extended system, in particular the realistic sampling of the entire Brillouin zone, the pulse propagation in the dense medium, and the inhomogeneous illumination of the crystal, have a strong effect on the harmonic spectra.

Intersubband gain in a Bloch oscillator and Quantum cascade laser
TL;DR: In this article, the link between the inversion gain of quantum cascade structures and the Bloch gain in periodic superlattices is presented, and the proposed theoretical model based on the density matrix formalism is able to treat the gain mechanism of Bloch oscillator and Quantum cascade laser on the same footing by taking into account in-plane momentum relaxation.
