The technique of stimulated Raman adiabatic passage (STIRAP), which allows efficient and
selective population transfer between quantum states without suffering loss due to …

Coherent preparation by laser light of quantum states of atoms and molecules can lead to
quantum interference in the amplitudes of optical transitions. In this way the optical …

We demonstrate that a cancellation of absorption occurs on resonance for two (or any even
number of) coupled optical resonators, due to mode splitting and classical destructive …

We study optical bistability (OB) behavior based on intersubband transitions in asymmetric
double quantum wells (QWs) where tunneling-induced quantum inference can be observed …

A hallmark of wave–matter duality is the emergence of quantum-interference phenomena
when an electronic transition follows different trajectories. This type of interference results in …

When Einstein showed that light amplification needed a collection of atoms in 'population
inversion'(that is, where more than half the atoms are in an excited state, ready to emit light …

The application of femtosecond spectroscopy to the study of ultrafast dynamics in
semiconductor materials and nanostructures is reviewed with particular emphasis on the …

We report an experimental demonstration and theoretical analysis of electromagnetically
induced transparency in a GaAs quantum well, in which the absorption of an exciton …

We present a classical analog of electromagnetically induced transparency occurring when
light is absorbed by a two-dimensional lattice of metallic spheres mounted on an asymmetric …

We propose a scheme to demonstrate spatiotemporal-vortex four-wave mixing (FWM) in an
asymmetric semiconductor double quantum-well nanostructure. It is found that the orbital …
