This article reviews the current knowledge on the main properties and applications of
hydrogen in LiNbO3. The review is divided into three parts. The first is devoted to general …

Photorefractive materials combine photoconductive and electro-optic properties: light affects
their electrical conductivity; their optical properties (refractive index, etc.) are affected by …

A problem of pulse propagation in a homogeneous nonlinear waveguide array with
saturable nonlinearity is studied. The corresponding model equation is the discretized …

We present a comprehensive analysis of the evolution of a grating envelope, in both
transmission and reflection geometry, during the erasure process in various readout …

We develop a theory of high-temperature photorefractive phenomena in LiNbO 3 crystals
related to the problem of thermal fixing and storage of optical information. The theory covers …

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

A scheme using a laser beam to thermally fix selective layers or lumps of photorefractive
holograms to integrate and miniaturize an optical three-dimensional system into a single …

With emphasis on LiNbO 3 the basic principles, the developments over four decades, and
recent applications of the thermal fixation of photorefractive holograms are reviewed …

We report what we believe to be the first observation of photorefractive gratings in lead
barium niobate (Pb_1-xBa_xNb_2O_6; PBN).? A diffraction efficiency of 9% and a beam …

The dynamic behavior of the complementary space-charge gratings formed in a
Bi_12SiO_20 crystal through prolonged recording at 780 nm is used to determine a number …
