Abstract

We measured the nonlinear optical susceptibility χ ( 3 ) of some Ge-Ga-Sb-S chalcogenide glasses feasible for the fabrication of highly nonlinear photonic crystal fibers. The χ ( 3 ) values of Ge 17 Ga 4 Sb 10 S 69 , Ge 20 Ga 5 Sb 10 S 65 , and Ge 20 Ga 5 Sb 6 S 69 glasses were found to be 3.5, 2.6, and 1.8 × 10 19 m 2 / V 2 (6.3, 4.6, and 3.2 × 10 12 esu , where “esu” stands for electrostatic unit) at the fundamental wavelength λ = 1.9 μm , i.e., 227, 167, and 117 times higher than that of standard silica [ 1.55 × 10 21 m 2 / V 2 ( 2.79 × 10 14 esu )]. Their nonlinear refractive indices n 2 were then obtained as 1.8, 1.3, and 1 × 10 17 m 2 / W (5.1, 3.7, and 2.7 × 10 11 esu ). They are 78 , 56, and 43% of n 2 = 2.3 × 10 17 m 2 / W ( 7 × 10 11 esu ) of the As 2 S 3 glass used as the chalcogenide glass reference.
