Abstract
The layered spiral microstructured optical fiber (LS-MOF) design allows higher nonlinearities than the most common microstructured optical fibers. Here, we have chosen a highly nonlinear glass for its composition, the arsenic trisulfide, and we have determined its dispersion and nonlinear characteristics. After adjusting the fiber’s parameters, we obtained a record value for the nonlinear parameter of 50.7[Formula: see text]W[Formula: see text]m[Formula: see text], at 1.550[Formula: see text][Formula: see text]m. We have simulated light propagation under these optimized circumstances, achieving a broad supercontinuum, extending from 500[Formula: see text]nm to 3900[Formula: see text]nm, in a very short distance: 0.3[Formula: see text]mm.
