The demonstrate the storage of 1000 holograms in LiNbO3:Fe, recorded at 488nm and read at 633nm to reduce decay during read-out. We minimize Bragg mismatch problems of the two-wavelength scheme by using thin crystals, while combining peristrophic and angle ...

Scattering rates of quantum-well excitons by acoustic phonons are calculated using realistic deformation potentials for electrons and holes in structures based on GaAs. These fates are used in order to reproduce the exciton dynamics in a time-resolved phot ...
A theoretical investigation of the dynamics in a photoluminescence experiment in strong-coupling semiconductor microcavities is presented. Radiative recombination rates of microcavity polaritons in the strong-coupling regime and their scattering rates with ...
We calculate scattering rates of QW excitons by acoustic phonons using realistic deformation potentials for electrons and holes in structures based on GaAs. We use these rates in order to reproduce the exciton dynamics in a time-resolved photoluminescence ...
We report measurements of the holographic diffraction efficiency (HDE) of single photorefractive gratings fixed by an externally applied voltage pulse in Sr0.75Ba0.25Nb2O6. The polarization grating HDE and decay rate are strongly dependent on the grating s ...
The photoprocesses of N-vinylcarbazole (NVC) solubilized in the interior of an oil-in-water microemulsion (CTA-ci, hexadecyltrimethylammonium counter ion) functionalized by an oxidizing agent, S2O2−8, were studied using ruby laser and spectrofluorimeter te ...
