Enhancement of optical rectification in coupled quantum wells
The nonlinear optical rectification (OR) in the asymmetric GaAs/AlxGa1−xAs coupled quantum wells (CQWs) is theoretically investigated. The compact density matrix approach and the iterative method are used to calc...

Tunable enhancement of harmonic radiation in coupled quantum wells
A few-cycle ultrashort laser field propagating through strongly coupled quantum wells (CQW) is numerically investigated. The results show that the harmonic signal can be tuned by the structure-control of CQW o...

Influence of frequency detuning on carrier-wave Rabi flop-related phenomena in the extreme nonlinear optics regime
In a simplified two-level atom or atomic-like system, resonantly interacting with laser, the so-called carrier-wave Rabi flop occurs accompanied by the occurrence of higher spectral components when the Rabi f...

Control of the carrier-envelope-phase effect in the transmitted spectra in quantum wells via terahertz waves
The propagation of a short pulse through an ensemble of semiconductor double quantum wells is theoretically investigated, and that whether the transmitted spectrum is discrete or continuous strongly depends on...
