Microstructured Optical Fibers Made of Chalcogenide Glass for the Generation of Optical Functions

This work reports on the fabrication and optical characterization of microstructured optical fibers (MOF) made of chalcogenide glass AS2S3. For the fabrication, the Stack and Draw method was used and for the characterization, a simulation software (OptiSystem) was also used. The results of this study are as follows: the refractive index of the microstructured chalcogenide glass fibre is 1.1.10-18 m2/w much higher than that of standard silica fibre, which is 2.6 10-20 m2/w. The non-linear refractive index of these chalcogenide fibers provided to be 100 times higher than that of the standard fiber. The characterization of the Brillouin and Raman diffusion effects also gave excellent results, with respective gain values of 8.10-10 W-1 Km-1 and 1.8.10-10 W-1 Km-1, thus validating an exacerbation of the non-linear effects within this type of fiber. These results were then used to generate optical functions.
