We have for the first time demonstrated two‐beam coupling energy transfer at a wavelength
of 1.5 μm. Beam coupling gain coefficients of 0.6 cm− 1 have been obtained in vanadium …

We report large enhancement of the two-beam-coupling gain in vanadium-doped cadmium
telluride. We used the applied-alternating-field method with square and sinusoidal …

The first study of the photorefractive properties of doped CdTe has demonstrated high
sensitivity for optical processing applications. Of the binary II‐VI and III‐V semiconductors …

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 …

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 …

A study of the mechanisms underlying the origin of near-band-edge photoreflectance (PR) in
CdTe is reported. We find that multiple transitions, including excitons, must be considered to …

Electron paramagnetic resonance (EPR), photo-EPR, optical absorption, and
photoluminescence measurements have been made on photorefractive vanadium-doped …

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 report here for the first time, two‐beam coupling energy transfer using the Franz–
Keldysh electrorefractive effect in photorefractive semiconductors. A large beam coupling …

Measurements and theoretical calculations are presented for the photorefractive effect in
three semi-insulating semiconductors (GaAs: EL2, InP: Fe, and CdTe: V) using 29-psec …
