Cross Section Design of Holey Optical Fibers with Coating Based on Stress Analysis in Tension

摘要

In this paper, the mechanical behavior of newlyuddeveloped holey optical fibers with and without coatingudwas investigated by numerical analysis. Based onudexperimental work, the tensile failure characteristics wereudobserved. The stress characteristics of some typical holeyudfibers with different section design were studied thoughudthe finite element method under tensile load. Theudoptimum design of air hole arrangements and sizes wereudproposed according to the numerical results. The influenceudof the coating thickness on the axial stress of holeyudoptical fiber was also investigated. The numerical resultsudand conclusions will be useful for the cross sectionudoptimum design of holey optical fiber for increase itsudstrength.
