In this paper the most important properties of lithium niobate crystals for photonic
applications are reviewed. We will summarize how acting on the stoichiometry, sample …

The lifetime of thermally fixed holograms in iron-doped lithium niobate is extensively studied
for samples with different iron oxidation state and hydrogen concentrations. The results …

We propose the use of fractal structured diffractive masks as keys in secure storage-readout
systems. A joint transform correlator based on a photorefractive crystal in the Fourier domain …

The two-color photorefractive properties in undoped as-grown near-stoichiometric lithium
tantalate crystals were investigated, where a near-infrared laser and a cw ultraviolet beam …

Experimental results on the diffraction efficiency of fixed holograms in undoped B i _2 T e O
_5 are presented. Gratings were recorded at room temperature, and using a 532 nm …

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 …

In this paper, we report the analysis of the recording (at room temperature), the fixing (at high
temperature) and the developing (at room temperature) procedures of high frequency …

This contribution reviews the present knowledge on photorefractive thermal fixing,
considering phenomena and their applications to long-lifetime holographic devices. Most …

We report the use of a polymer-based photorefractive material for three-dimensional bit
optical data storage using near-infrared illumination. The research was conducted using …
