Large photorefractive two-wave mixing gain in CdZnTe: V at a 1.5-μm wavelength is
demonstrated with an external dc field and a third incoherent stimulating beam of 1.3-μm …

We present new results on the growth of semi-insulating vanadium-doped cadmium telluride
crystals and their characterization by different optical techniques such as photoinduced …

We report on the observation of photorefractivity in vanadium-doped zinc telluride in the 0.63-
1.3-pm-wavelength range. Photorefractive two-beam coupling, along with …

Vanadium‐doped CdTe has recently been shown to have a high sensitivity for optical
processing at 1.5 μm but the role of the vanadium dopant has been questioned. We present …

We report observations of the photorefractive effect in vanadium-doped Cd 0.55 Mn 0.45 Te.
The photorefractive response was observed in the red and near infrared, over the broad …

For optical telecommunication networks, optical switching is now being studied. Different
solutions have been proposed (integrated optics, free space switching, etc.), and …

Tin is shown to be a suitable dopant that makes it possible to grow cadmium telluride
crystals with considerably reduced conductivity (semi‐insulating material) and ensures a …

Electron paramagnetic resonance spectroscopy, secondary-ion mass spectrometry, and
moving space charge field techniques were used to characterize semi-insulating cadmium …

Deep levels in vanadium-doped CdTe and CdZnTe crystals grown by vertical Bridgman for
photorefractive applications are reviewed. Based on photo-induced current transient …

The photorefractive nonlinearity associated with the Dember space-charge field between
electrons and holes produced by two-photon absorption is unambiguously isolated and …
