Lead-germanate glasses and fibers: A practical alternative to tellurite for nonlinear fiber applications
(2013-09-20)
We report on the fabrication of novel lead-germanate glasses and fibers. We have characterized these glasses in terms of their thermal properties, Raman spectra and refractive indices (both linear and nonlinear) and present ...

Caracterização ótica não-linear em cerâmicas ferroelétricas transparentes (CFT s) de PLZT: TR (TR = nd,Ho, Er, Tm e Yb)
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2009-10-02)
Lead titanate zirconate modified with lanthanum, or PLZT, is one the most ferroelectric compounds utilized in electronic devices, due to its versatility and low production costs in comparison with single-crystalline ...
Estudo da incorporação de nanopartículas de óxido de zinco e pentóxido de nióbio em polietileno linear de baixa densidade
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2019-03-29)
Linear low-density polyethylene (LLDPE) is one of the most widely used materials in greenhouse covering, due to its low cost and transparency to photosynthetically active radiation up to 80%. However, this polymer also ...
Antimony glasses with large nonlinear refractive indices, small two-photon absorption coefficients and ultrafast response at telecom wavelengths
(2007-12-01)
Nonlinear (NL) optical properties of antimony oxide based glasses (AG) were characterized for excitation wavelengths from 800 to 1600 m. The NL refractive indices, n2, and the two-photon absorption (TPA) coefficient, β, ...

Analysis and measurement of the non-linear refractive index of SiOxNy using pedestal waveguides
(Ieee, 2019-01-01)
In this work, the non-linear refractive index (n(2)) of silicon oxynitride (SiOxNy) is determined, obtaining a value for this material of n(2) = 2.11x10(-19) m(2)/W. The results demonstrate that this material has interesting ...
