Effect of spontaneously generated coherence on EIT and its refractive properties in four- and five-levels systems

Control of the optical multistability in a three-level ladder-type quantum well system

“…By adopting the standard approach [35,36,[40][41][42]46,47], the densitymatrix equations of motion in dipole and rotating-wave approximations for this system can be written as follows:…”

“…It should be worth pointing out that a great deal of nonlinear quantum optical phenomena based on the quantum interference and coherence are also been extensively studied in the semiconductor quantum wells (SQWs) in recent years [34][35][36][37][38][39][40][41][42][43][44][45][46][47], such as gain without inversion [34][35][36], electromagnetically induced transparency [37][38][39][40]46], optical bistability [41,42], Kerr nonlinearity [43], optical soliton [44], four-wave mixing [45]. The reason for this is mainly the phenomena in the SQWs have many potentially important applications in optoelectronics and solid-state quantum information science.…”

Control of the probe absorption via incoherent pumping fields in asymmetric semiconductor quantum wells

“…By adopting the standard approach [27][28][29]33,34], the density-matrix equations of motion in dipole and rotating-wave approximations for this system can be written as follows:…”

“…It should be 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) [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35], such as gain without inversion [21][22][23], electromagnetically induced transparency [24][25][26][27]33], optical bistability/multistability [28,29], Kerr nonlinearity [30], optical soliton [31], four-wave mixing [32], and so on. The reason for this is mainly that the phenomena in the SQWs have many potentially important applications in optoelectronics and solid-state quantum information science.…”

The influence of spontaneously generated coherence on atom-photon entanglement in a Λ-type system with an incoherent pump

“…Here the relative phase stems from the SGC effect [34,35]. In particular, the SGC effect is one of the most representative dissipative processes [36][37][38]. Generally, narrowing down the decay rate is expected.…”
