Paper Abstract

Faraday rotator glasses with high Verdet constants are used for optical isolators and sensors. Based on the Tb2O3 -B2O3-Al2O3- SiO2 system and the effect of each component on glass formation, glass compositions were selected for development of new Faraday rotator glasses. Devitrification of Tb-glass was studied by microscopic morphology to establish the production process. Dispersion of Verdet constant and the influence of Tb3+ concentration on Verdet constant were investigated. Special technology was utilized for production of platinum-free glass. The quenching process is necessary to obtain crystal-free glass. Three kinds of Faraday rotator glass with higher Verdet constant than that of M16 have been developed. The higher Verdet constant glass is possible to obtain.
