Abstract
The off-resonance Raman spectra of , , , , , and 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 glass proposed for highly nonlinear microstructured optical fibers. We calculated the Raman response functions of , ; and , glasses. The supercontinuum generation of a three-air-hole fiber was simulated, challenging the properties of a similar fiber design made of chalcogenide glass. We calculated the zero dispersion wavelengths of fibers with the core diameters of 1.2, 1.5, and at , 1.66, and in comparison with , 1.87, and obtained for fibers.
