Mid-infrared efficient generation by resonant four-wave mixing in a three-coupled-quantum-well nanostructure

Phase-dependent optical bistability and multistability in a semiconductor quantum well system

“…It is worth pointing out that many kinds of nonlinear quantum optical phenomena based on the quantum interference and coherence have also been extensively studied in the semiconductor quantum wells (SQWs) in recent years [44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62], such as gain without inversion [44][45][46][47], electromagnetically induced transparency [48][49][50][51], optical bistability [52,53], Kerr nonlinearity [54], optical soliton [55,56], and four-wave mixing [57]. The reason for this is mainly that the phenomena in the SQWs have many potentially important applications in optoelectronics and solidstate quantum information science.…”

Electromagnetically induced transparency and theoretical slow light in semiconductor multiple quantum wells

“…We It is well known [18][19][20] that many-body effects in solids lead to the renormalizations of decay or decoherence or relaxation rates, energy levels, and the control field. The simple analytical results in (11)-(14) express the propagation characteristics of the probe field for the cascade-type threelevel system of 15-period GaAs/Al 0.3 Ga 0.7 As MQWs explicitly in terms of these parameters (notice that the renormalization of energy levels can be accounted for by the detuning) and hence provide a convenient basis for investigating how the many-body effects in solids modify the magnitude, spectral shape, and space-time dependence of the EIT and EIT-related quantum coherence phenomena in solids [10][11][12][13]20].…”

Coherent laser-induced optical behaviors in three-coupled-quantum wells and their application to terahertz signal detection

“…Consequently, we assume that many body effects arising from electron-electron interactions are not included in our study. This method has described quantitatively the results of several experimental papers [9,13,16,23,25,26] and has been used in several theoretical literature [7,8,11,14,15,17,32,34]. As a matter of fact, the effects of electron-electron interactions in the dynamics of ISBTs in semiconductor QWs have been studied in several recent publications, see e.g.…”
