O objetivo deste projeto de mestrado é construir um interferômetro para medidas de
vibraçao mecânica em 2D utilizando cristais fotorrefrativos como sensor. Além disso, foi …

Czochralski crystal growth is one of the major methods of crystal growth from melt for bulk
single crystals for commercial and technological applications. Most crystals, such as …

Holographic data storage based integer OAM beams with different values of topological
charges on a Photorefractive Crystal (PhRC) through a Mach Zehnder interferometer is …

Holographic polymer-dispersed liquid crystals are promising materials for switchable
holograms, optical data storage, tunable beam deflectors and various diffractive optical …

We used a digital feedback control loop system to produce reproducible fixed volume
transmission holograms of high diffraction efficiency. Different strategies were investigated to …

The lifetime of the excited charge carriers in Rh-doped BTO crystals is characterized by
measuring the time-resolved photoinduced absorption (PIA) after nanosecond pulse …

A succinct but clear introduction of the photorefractive solitons has been presented in this
chapter. The electro-optic effect has been explained with a relevant example which then …

The primary challenge throughout the history of holographic data storage (HDS) has been
the development of a recording material that could enable the promise of this technology …

Efeitos não lineares são discutidos desde o final do século passado com os avanços da
física moderna, que permitiu a invenção do laser e a descoberta de cristais fotônicos. O …

We report holographic recording in thick phenanthrenequinone-doped poly (methyl
methacrylate)(PQ/PMMA) photopolymer material via the two-wavelength technique. By …
