Abstract We have studied two-dimensional absorption and gain spectrum in an asymmetric semiconductor triple-coupled-quantum-well (TCQW) nanostructure. Four subband transitions are coupled by using four coherent fields in a close-loop configuration to

We have proposed two schemes to exhibit -antisymmetry in a four-level N-type atomic system interacting with two strong driving fields and a weak probe field. For both the schemes, the required spatially modulated coherence rendering -

We propose an atomic model in close-loop configuration, which exhibits controllable symmetric and asymmetric evolution of significantly enhanced diffraction peaks of the weak probe beam in an opto-atomic grating at far-field regime. Such results are

A new approach for achieving two – dimensional (2D) atom localization microscopy based on the projection of three – dimensional (3D) localization in the plane of the detector is described in the present work. Spatial variation of the position-dep

A scheme is proposed to realize three-dimensional (3D) atom localization in a driven two-level atomic system via resonance fluorescence. The field arrangement for the atom localization involves the application of three mutually orthogonal standing-wa

The optical analogue of quantum population dynamics in a three-level atom is theoretically demonstrated by employing a specially designed macroscopic photonic structure composed of three evanescently coupled straight waveguides. We have developed the

In this article, simultaneous interaction of two side-coupled waveguides is considered with the dressed continuum represented by a linear waveguide array in which two consecutive pairs of waveguides are coupled in phase (positive coupling) and out-of
