Wavelength Dispersions of the Faraday Effect in Chalcogenide Glasses

Abstract

Chalcogenide glasses of As₂₀S₈₀, Ge₂₀As₂₀S₆₀, As₄₀S₆₀ and As₄₀S₅₇Se₃ were prepared. The wavelength dispersions of the Faraday effect for these glasses were examined. The Verdet constants of the glasses decreased at wavelengths longer than the absorption edge of the glasses. The values of the Verdet constants of the glasses were in the order of As₂₀S₈₀<Ge₂₀As₂₀S₆₀<As₄₀S₆₀<As₄₀S₅₇Se₃, which were successfully confirmed on the basis of the Becquerel theory.
