Recent Advances in the Photorefraction of Doped Lithium Niobate Crystals
The recent advances in the photorefraction of doped lithium niobate crystals are reviewed. Materials have always been the main obstacle for commercial applications of photorefractive holographic storage. Though iron-doped LiNbO3 is the mainstay of holographic data storage efforts, several shortcomings, especially the low response speed, impede it from becoming a commercial recording medium. Thi...
متن کاملX-ray-induced conductivity in iron-doped lithium niobate crystals
Illumination of photorefractive, iron-doped lithium niobate crystals (LiNbO3 :Fe) with x-rays generates a conductivity that we determine from the speed of hologram erasure. The doping levels of the crystals and the acceleration voltage of our x-ray tube are varied. A theoretical model is presented, which describes the obtained results. A decrease of the conductivity with increasing Fe concentra...

متن کاملCharacterization of erbium doped lithium niobate crystals and waveguides
Optical planar waveguides have been fabricated by the titanium in-diffusion process in lithium niobate crystals activated with erbium ions. The waveguides were studied by m-line technique in order to recover the index profile. The effect of the Ti in-diffusion on the structural and spectroscopic properties of the lithium niobate crystals was investigated by Raman and photoluminescence spectrosc...
متن کاملHolographic properties of doubly doped lithium niobate crystals with Indium
The holographic properties of doubly doped lithium niobate crystals with Indium have been investigated. It is found that doping slight Indium concentration (0.5mol%) in LiNbO3:In, Fe crystal can efficiently increase the sensitivity with small dynamic range changing. To improve the whole holographic properties of LiNbO3 crystal, LiNbO3:In, Fe with ideal doping concentrations and a new photorefra...
