Self-Consistent Study of GaAs/AlGaAs Quantum Wells with Modulated Doping

Nanomaterials, 2023
In this work, the characterization and analysis of the physics of a GaAs quantum well with AlGaAs barriers were carried out, according to an interior doped layer. An analysis of the probability density, the energy spectrum, and the electronic density was

Plasmon Assisted Transparency in Metal--Dielectric Microspheres [PDF]

, 2006
We present a theoretical analysis of light scattering from a layered metal-dielectric microsphere. The system consists of two spherical resonators, coupled through concentric embedding.

Effects of temperature and ground-state coherence decay on enhancement and amplification in a $\Delta$ atomic system

, 2014
We study phase-sensitive amplification of electromagnetically induced transparency in a warm ${}^{85}$Rb vapor wherein a microwave driving field couples the two lower-energy states of a {\Lambda} energy-level system thereby transforming into a {\Delta ...

Radiation trapping in coherent media [PDF]

, 2001
We show that the effective decay rate of Zeeman coherence, generated in a Rb87 vapor by linearly polarized laser light, increases significantly with the atomic density. We explain this phenomenon as the result of radiation trapping.

Electromagnetically Induced Transparency from a Single Atom in Free Space

, 2010
We report an absorption spectroscopy experiment and the observation of electromagnetically induced transparency from a single trapped atom. We focus a weak and narrowband Gaussian light beam onto an optically cooled Barium ion using a high numerical ...

Electromagnetically induced transparency of ultralong-range Rydberg molecules [PDF]

, 2017
We study the impact of Rydberg molecule formation on the storage and retrieval of Rydberg polaritons in an ultracold atomic medium. We observe coherent revivals appearing in the retrieval efficiency of stored photons that originate from simultaneous ...

Tuning Electromagnetically Induced Transparency in a Double GaAs/AlGaAs Quantum Well with Modulated Doping

Crystals
Including an n-doped layer in asymmetric double quantum wells restricts confined carriers into V-shaped potential profiles, forming discrete conduction subbands and enabling intersubband transitions.
