Abstract

The wavelength dispersion of the Verdet constants of bulk As-S, As-Se-S, Ge-As-Se and Ga-La-S-based chalcogenide glasses has been investigated at wavelengths between 675 and 1550 nm. Ge₃₃As₁₂Se ₅₅ was found to have the highest Verdet constant, 0.0485 min/G.cm at 1550 nm, 30 times that of silica. The high Verdet constant of Ge ₃₃As₁₂Se₅₅ is related to its smaller band gap energy compared with the other glasses. Further improvement of the Verdet constants of the Ge-Se-based chalcogenide glasses by engineering their compositions could make them promising materials for integrated magneto-optical devices.
