Abstract: The wavelength dispersion of the magneto-optical properties of bulk As-S, As-Se-S, Ge-As-Se and Ga-La-Sbased chalcogenide glasses have been investigated at visible and infrared wavelengths. Ge33As12Se55 was found to have the highest Verdet constant, corresponding to the lowest band gap energy compared with the other chalcogenide glasses. Its Verdet constant is 0.0485 min/G_cm at 1550nm, 30 times that of silica, and is the highest Verdet constant reported to date for chalcogenide glasses. Further improvement of the Verdet constants of the Ge-Se-based chalcogenide glasses by engineering of their compositions will make them a very promising material for future integrated magneto-optical devices.
