Phase-dependent coherent population trapping and optical switching
TLDR
In this article, a scheme for achieving phase-dependent coherent population trapping was proposed, showing that both the dark state of the atoms and light propagation dynamics depend on the relative phase of the fields.Abstract:
We propose a scheme for achieving phase-dependent coherent population trapping, showing that both the dark state of the atoms and light propagation dynamics depend on the relative phase of the fields. The atomic coherence prepared via adiabatic process plays a key role in the interaction of light with matter. And an optical switching based on the phase-controlled quantum interference is implemented, which may have potential application in high-speed optical communications and quantum information systems.read more

Coherent manipulation of spontaneous emission spectra in coupled semiconductor quantum well structures
TL;DR: In triple coupled semiconductor quantum well structures (SQWs) interacting with a coherent driving filed, a coherent coupling field and a weak probe field, spontaneous emission spectra are investigated and it is shown they can easily be manipulated through changing the intensity of the driving and coupling field.
