Torsion of Air-hole Microstructured Fiber Devices under LargeDefection

摘要

This paper studies torsion of air-hole microstructured fibers induced by fiber packaging. The twist of two-hole optical fiber induced while the fibers were coiled into a helix along the surface of a cylinder was experimentally observed and simulated using the Finite Element Analysis. Both experiment and simulation reveal periodic twisting patterns when two holes fibers were coiled along the surface of a cylinder.
