Abstract

Magneto-optical properties of tellurium-arsenic-selenium glass (Te₂₀As₃₀Se₅₀) were measured and analyzed. A Verdet constant of 15.18 rad/T/m at 1950 nm with the figure of merit of more than 8.72 rad/T, which is the highest value reported in glass materials at this wavelength, was measured. Compared to other chalcogenide glasses, such as Ge₁₀Se₉₀ and Ge₂₅As₁₅S₆₀, Te₂₀As₃₀Se₅₀ glass exhibits higher Verdet constants, broader mid-infrared transparency window, and longer infrared absorption edge, making it a very promising material to fabricate magneto-optical devices for mid-infrared applications.
