Abstract

Low- and high-refractive-index chalcogenide glasses are studied for their potential use in the fabrication of one-dimensional hollow Bragg fibers. The low-index glasses are based on the GeSe–glass systems with indices varying from 2.0 to 2.5, while the high-index glasses are formed from the AgAsSe glasses with indices ranging from 2.8 to 3.8. High-purity elemental starting materials are distilled and the surface oxides removed prior to mixing in a rocking furnace. The refractive indices of the AgAsSe glasses, measured using a CO 2 laser reflectometer, were near 3.10 for the compositions most compatible with the low-index Ge 20 Se 80 glass ( n = 2.46 ). Spectral measurements show impurity absorption bands between 12 and 16 μm . The loss at 10.6 μm for the Ag 25 As 40 Se 35 glass measured using CO 2 laser calorimetry was 1.16 × 10 3 cm 1 .
