Wavelength dispersion of Verdet constants in chalcogenide glasses for magneto-optical waveguide devices
Abstract
<p>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. Ge<sub>33</sub>As<sub>12</sub>Se <sub>55</sub> 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 <sub>33</sub>As<sub>12</sub>Se<sub>55</sub> 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.</p>
