Journal ArticleDOI
Subwavelength atom localization via amplitude and phase control of the absorption spectrum-II
TL;DR: In this paper, a scheme for sub-half-wavelength localization of an atom conditioned upon the absorption of a weak probe field at a particular frequency was proposed, where one of the drive fields is a standing-wave field of a cavity.
Journal ArticleDOI
Tunable phase control for subluminal to superluminal light propagation
TL;DR: In this paper, the authors demonstrate tunable control of the group velocity of a weak probe pulse from subluminal to superluminous, using an extended ε-Lambda-type system with two extra control fields and an extra energy level.
Journal ArticleDOI
Enhanced Kerr nonlinearity in a tunnel-coupled double quantum wells
TL;DR: In this paper, the giant Kerr nonlinearity in an asymmetric coupled quantum well (CQW) driven by probe and control laser fields based on intersubband transitions is investigated.
Journal ArticleDOI
The effects of the incoherent pumping field on the phase control of group velocity
TL;DR: In this article, the effects of the incoherent pumping field and spontaneously generated coherence (SGC) on the phase control of group velocity were studied and the effect of a relative phase between probe and coupling fields on the absorption and the dispersion were discussed.
Journal ArticleDOI
Subluminal and superluminal light propagation via interference of incoherent pump fields
TL;DR: In this article, the dispersion and the absorption properties of a weak probe field in a four-level atomic system were investigated using the incoherent pumping fields, and it was shown that the slope of dispersion changes from positive to negative with the interference of the coherent pumping process.
