The photorefractive properties of CdTe and CdZnTe alloys are reviewed. Firstly, the energy
level spectrum of the deep centre vanadium is analyzed from the data brought about by …

We propose a time-dependent three-dimensional numerical model which successfully
explains the complex spatiotemporal dynamic of photorefractive self-focusing of an infrared …

La souplesse d'emploi des matériaux photoréfractifs est un de leurs principaux attraits. Un
même échantillon est sensible sur une plage de longueurs d'onde de plus de 100 nm avec …

This paper extends the existing theory of two-carrier photorefractivity resonance, which is
generally applied to iron doped indium phosphide (InP: Fe), to the case of low nonharmonic …

This paper reports an experimental study of the self-focusing process in iron doped indium
phosphide at an 1.06 micron wavelength, identifying the influence of temperature, beam …

Two-wave mixing in photorefractive InP: Fe crystals is revisited in terms of an externally
applied dc field combined with the moving-grating technique. We show that the …

Der ständig wachsende Bedarf an Rechenleistung und Speicherplatz stößt langsam an die
Grenzen elektronischer Systeme. Die weltweit anschwellenden Datenströme der modernen …

L'objectif de cette thèse a été l'évaluation de deux semi-conducteurs (l'InP: Fe et le SPS: Te)
comme matériaux pour les télécommunications optiques aux longueurs d'ondes …

The photorefractive effect in semiconducting materials with multiple defects is studied in the
case of modulation depth m= 1. The basic equations are Poisson's equation and the …

Analytically and numerically we investigate the dependence of the first Fourier harmonics of
the space-charge field, induced in an AC-biased sillenite crystal by a light-interference …
