Refractive Index Sensing of Temperature in a Nanostructure Fiber

Abstract

Mohammed Salim Jasim AL-Taie

Nanostructure fibers were the focus of much research and study due to their simple nature of manufacture and construction. As this study demonstrated, several parameters are employed in that structure that can influence the refractive index of the electromagnetic pulse propagating, including their diameter, number, and spacing between the holes. It was also investigated how temperature affected the refractive index. Researchers have shown that the refractive index rises with increasing air hole diameter and falls with increasing air hole spacing. The number of air holes appears to have no discernible impact on refractive index. Regarding temperature, it is directly correlated with both frequency and intensity. Specifically, a rise in temperature causes the refractive index of the pulse traveling through this fiber to rise. Changing the temperature of the fiber is interesting for dynamics fine refractive index tuning in active refractive index shift compensation system. this paper presents a numerical analysis on the effect in this structure temperature on refractive index and modal features. the research depends on regular hexagonal crystal lattice fibers with specific geometric parameters using the finite element method.
