1. Amplificador e conversor de comprimento de onda hÃbrido TDFA/FOPA para comunicaÃÃes Ãpticas
A regiÃo de comprimento de onda do espectro eletromagnÃtico usado nas telecomunicaÃÃes Ãpticas sÃo definidas pela International Telecommunications Union (ITU) como, banda C (Conventional Band, 1530-1565 nm), banda L (Long Wavelength Band, 1565- 1625 nm), banda S (Short Wavelength Band, 1450-1530 nm), e bandas mais distantes de ambos os lados da banda C

2. POLARIZAÇÃO ELETROTÉRMICA DE VIDROS E FIBRAS ÓPTICAS / GLASS AND OPTICAL FIBER ELECTROTHERMAL POLING
Over the past few years, there has been a growing demand for optical components for telecommunication systems. In order to increase the efficiency of these components, reduce costs and allow integration to current systems, efforts have been made in researching new materials, for example, silica. Due to its isotropic nature, silica, ordinarily, does not prese

3. Fabricação e caracterização de vidros dopados com quantum dots de PbTe
In this work, we make a description and analysis of the fabrication method s of the PbTe quantum dots (QD) doped glasses and characterization techniques used by study the properties of the glasses. We have prepared glasses doped with 5 and 10 % of PbTe respectively. The characterization was by Scanning Electron Microscopy (SEM), High Resolution Transmission
