Electrical conductivity of Ge10 Se90-x Bix (x=0,2,4,6,8,10) glassy systems prepared by melt quenching technique has been studied at different temperature in bulk form through I-V characteristic curves. It has been observed that the electrical conductivity... see more

Applications involving optical fibers have grown considerably in recent years with intense levels of research having been focused on the development of not only new generations of optical fiber materials and designs, but also on new processes for their pr... see more

We study the impact of geometry on leakage loss in negative curvature fibers made with As 2 Se 3 chalcogenide and As 2 S 3 chalcogenide glasses for carbon dioxide (CO 2 ) laser transmission. The minimum leakage loss de... see more

In the present research work melt quenching method has been adopted to prepare the glassy Te-rich (Te90Se10) and Se-rich (Se90Te10) Chalcogenide at a pressure of 10-2 Torr with constant Temperature at 1000C for 8 hours. Devitrification characteristics of ... see more

A review on the recent progress in modeling and fabrication of medium infrared (Mid-IR) fiber lasers is reported. The main objective is to illustrate some recent examples of continuous wave optical sources at wavelengths longer than those commonly employe... see more


This article is devoted to the study of the influence of moisture in sandwich structure Al-As33.3Se33.3S33.4-Te, Al-As33.3Se33.3S33.4:Smx-Te (x=1 at%).It is clear from the analysis of schedules, after thermal annealing time characteristics is improved for... see more

This work aimed to synthesize, characterize and evaluate the thermal stability of new sulfur and selenium organochalcogenide derivatives and to test the cytotoxic activity against breast adenocarcinoma cell line (MCF-7) through conducting MTT assay and AO... see more
