“…Holographic storage has garnered a considerable research interest due to its potential future applications and is studied by many researchers from an extended period. The superior competence of holographic storage involves its high storage capacity and faster data transfer rate [7,8,9,10,11]. Recently, much research is also directed toward the photorefractive polymers and other organic materials, due to their faster photorefractive (PR) responses and high sensitivities for holographic storage applications.…”

A series of mono-, double-, and tri-doped LiNbO3 crystals with vanadium were grown by Czochralski method, and their photorefractive properties were investigated. The response time for 0.1 mol% vanadium, 4.0 mol% zirconium, and 0.03 wt.% iron co-doped lithium niobate crystal at 488 nm was shortened to 0.53 s, which is three orders of magnitude shorter than the mono-iron-doped lithium niobate, with a maintained high diffraction efficiency of 57% and an excellent sensitivity of 9.2 cm/J. The Ultraviolet-visible (UV-Vis) and OH− absorption spectra were studied for all crystals tested. The defect structure is discussed, and a defect energy level diagram is proposed. The results show that vanadium, zirconium, and iron co-doped lithium niobate crystals with fast response and a moderately large diffraction efficiency can become another good candidate material for 3D-holographic storage and dynamic holography applications.

“…Films of polymeric composites with monomers of azobenzene dyes or polymers containing azobenzene groups exhibit photoactive properties. They can be used for creation of electro-optical light modulators and recording media (RM) for polarization holography [1][2][3][4][5]. The principle of recording in these media is based on photoinduced optical anisotropy (PIA) that appears in these films under illumination with linearly polarized light from the absorption range of trans-isomers.…”

“…In amorphous films, stable surface reliefs can be formed [5][6][7][8][9][10][11][12][13][14][15][16]. On the base of polymeric thin layers with azobenzene groups, one can develop many photonic elements, namely: diffraction gratings, arrays of microlenses, plasmon sensors, antireflection coatings, and nanostructured light polarization converters [1]. Holograms in these polymers are stable when stored below the softening temperature (T s ).…”

The recording media for polarization holography based on azobenzene polymers are obtained by polymer-analogous transformations of polymethacrylic acid and its copolymers with alkyl methacrylates. Their informational properties were investigated when recording holograms of a plane wavefront. It has been found that the recording and relaxation times of holograms are approximately the same. They are defined mainly by the processes of trans-cis-isomerization of azobenzene groups without formation of surface relief of the polymeric film. The efficiency of the trans-cis-isomerization process decreases, if a heavy substituent is present in the azobenzene chromophore. These results are of practical interest in the choice of photosensitive materials for holographic recording media with optimal information characteristics.

“…It is good to search those references, for example [ 4 , 5 , 6 ]. More recently a Review of photosensitive materials for holography has been published [ 7 ]. Besides the gelatin based materials, the review includes photopolymers, photochromics, photorefractive, liquid crystals and more.…”

Gelatin as a Photosensitive Material

et al. 2018

Because this issue journal is dedicated to Gelatin, here we present a few applications of gelatin in the field of optics. Optics is the science that studies the production, propagation, interaction and detection of light. Various materials sensitive to light (photosensitive) are used for detection of light, such as photomultipliers, CCDs, crystals, two dimensional (2D) materials and more. Among the 2D materials, the most popular for several centuries has been gelatin based photographic emulsion, which records spatial distributions of light. More recently (1970), films made of Gelatin with Dichromate (DCG) and dyes have been used. We describe some characteristics and applications of these two photosensitive materials. We also describe examples where gelatin is used as a Relative Humidity (RH) sensor and in the fabrication of optical elements based on gelatin. This article is intended for researchers outside the optics community.
