The photorefractive properties of two CdTe: V crystals are compared in the infrared range.
For both crystals, an increase of the electron-hole competition factor (from electrons to holes) …

The ac field technique leading to the enhancement of the photorefractive effect is applied to
vanadium-doped cadmium telluride. Net photorefractive gain is obtained for the three …

We present two-wave mixing results obtained with CdTe: V photorefractive crystals under an
external dc or low-frequency square-shaped periodic electric field. The majority …

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

Vanadium doped CdTe (CdTe: V) behaves as an efficient photorefractive material due to its
higher figure of merit (n3r41) than InP: Fe. It is a potential material for optoelectronic …

A way to interconnect optical fibers in a telecommunication network working between 1.3
and 1.55 micrometer is the use of two-wave mixing mirrors. These devices use the …

The photorefractive properties of CdTe and CdZnTe alloys are reviewed. Firstly, the energy
