Study of the glass transition temperature of as-s glasses for the fabrication of chalcogenide optical fibers
Values of glass transition temperature (Tg) and of linear expansion coefficient (α) for Asx S100-x glasses were measured in the range of concentrations 35 × 42. Because of the importance of the glass formation region 35 × 42 ...
Lead-germanate glasses and fibers: A practical alternative to tellurite for nonlinear fiber applications
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 ...
Evaluation of the flexural strength of carbon fiber-, quartz fiber-, and glass fiber-based posts
This study investigated the flexural strength of eight fiber posts (one carbon fiber, one carbon/quartz fiber, one opaque quartz fiber, two translucent quartz fiber, and three glass fiber posts). Eighty fiber posts were ...
Nonlinear effects generation in suspended core chalcogenide fibre
In this work we report our achievements in the elaboration and optical characterizations of low-losses suspended core optical fibers elaborated from As2S3 glass. For preforms elaboration, alternatively to other processes ...
Hybrid Vegetable/Glass Fiber Composites
There is an ever-growing worldwide interest in the use of lignocellulosic fibers as reinforcement in either thermoset (mainly unsaturated polyester) or thermoplastic (mainly polyolefins) composites. However, the wider use ...
