Abstract

The off-resonance Raman spectra of As 2 S 3 , GeS 2 , Ge 25 Ga 5 S 70 , Ge 23 As 12 S 65 , Ge 23 Sb 12 S 65 , and Ge 17 Ga 4 Sb 10 S 69 chalcogenide glasses have been recorded and the corresponding Raman gain coefficients have been calculated in order to evaluate the role of Ge, Ga, Sb, and As on a novel Ge 17 Ga 4 Sb 10 S 69 glass proposed for highly nonlinear microstructured optical fibers. We calculated the Raman response functions of As 2 S 3 n 2 = 2.3 × 10 17 m 2 / W , G 2.78 × 10 11 m / W ; and Ge 17 Ga 4 Sb 10 S 69 n 2 = 1.8 × 10 17 m 2 / W , G 1.57 × 10 11 m / W glasses. The supercontinuum generation of a three-air-hole Ge 17 Ga 4 Sb 10 S 69 fiber was simulated, challenging the properties of a similar fiber design made of As 2 S 3 chalcogenide glass. We calculated the zero dispersion wavelengths of Ge 17 Ga 4 Sb 10 S 69 fibers with the core diameters of 1.2, 1.5, and 2.0 μm at λ = 1.48 , 1.66, and 1.75 μm in comparison with λ = 1.60 , 1.87, and 1.98 μm obtained for As 2 S 3 fibers.
