硫系玻璃的非线性折射率比熔融石英高200倍，并提供远至中红外的透明窗口。这些特性使它们对波长超过2 μm的超连续统（SC）产生很感兴趣。文献中已经报道了多种不同的含硫系玻璃的波导结构，包括微结构光纤[1]和锥形光纤[2]。
Chalcogenide glasses have nonlinear refractive indices ~200 times greater than fused silica, and offer windows of transparency extending far into the mid-IR. These properties make them interesting for supercontinuum (SC) generation at wavelengths beyond 2 μm. Various different waveguiding structures incorporating chalcogenide glasses have been reported in literature, including microstructured fibers [1] and fiber tapers [2].
