We study optical bistability (OB) behavior based on intersubband transitions in asymmetric
double quantum wells (QWs) where tunneling-induced quantum inference can be observed …

Coherent interaction between light and matter generates photon-dressed replicas of the
original electronic levels (that is, Floquet states). This opens up a so-called field of Floquet …

When Einstein showed that light amplification needed a collection of atoms in 'population
inversion'(that is, where more than half the atoms are in an excited state, ready to emit light …

We study the low-intensity light pulse propagation through an asymmetric double quantum
well via Fano-type interference based on intersubband transitions. The propagation of the …

The near-infrared transmission of a semiconductor multiple quantum well is probed under
intense terahertz illumination. We observe clear evidence of the intraexcitonic Autler …

Femtosecond laser–driven photoemission source provides an unprecedented femtosecond-
resolved electron probe not only for atomic-scale ultrafast characterization but also for free …

An experiment-theory comparison is presented to demonstrate terahertz-induced extreme-
nonlinear transients in a GaAs/AlGaAs quantum-well system. The terahertz-pump and …

We demonstrated theoretically that the renormalization of the electron energy spectrum near
the Dirac point of graphene by a strong high-frequency electromagnetic field (dressing field) …

A quantum well (QW), with only three transitions, which are all dipole allowed because of the
QW asymmetry, is investigated when driven coherently by two infrared optical fields. One …

Semiconductor quantum well electroabsorption modulators are widely used to modulate
near-infrared (NIR) radiation at frequencies below 0.1 terahertz (THz). Here, the NIR …
