We here expose theoretical and experimental results on homodyne detection using near-
infrared laser sources, at 1.06, 1.32, and 1.55 μm wavelengths. The used photorefractive …

This article presents a review of active optical devices. We examine different technologies
that can be used for active wavefront modulation in a large range of applications including …

We study charge transients induced by optical pulses in CdTe detectors. Different carrier
dynamics and collection properties are observed in the signals induced by optical excitation …

Schottky CdTe X-ray detectors exhibit excellent spectroscopic performance but suffer from
instabilities. Hence it is of extreme relevance to investigate their electrical properties. A …

We demonstrate a self-adapting homodyne detection system working at a wavelength of
1.55 μm. The system uses a photorefractive CdTe: V crystal as the element that combines …

We present a summary of the experimental results, the attempts of interpretation at the
present stage, and the conclusions of coupled investigations on semi-insulating, n-type and …

An accurate determination of the effective trap density in CdTe: V is performed using both
counter-propagating (small grating spacing) and co-propagating (large grating spacing) two …

Photoexcited carrier and space charge field subnanosecond dynamics has been
investigated in bulk vanadium-doped and Cl-(or As-) co-doped CdTe crystals by using a …

We demonstrated for what is the first time to our knowledge photorefractive two-wave mixing
in a bulk ferroelectric crystal using cw light at the telecommunication wavelength 1.55 μm. In …
