Abstract

An interferometric method to study the induced variations of nonlinear parameters in bent optical fiber such as third-order susceptibility χ(3) and second-order refractive index n2 is presented. Due to the expected nonlinear response of the Young’s modulus of fiber material, the profiles of asymmetric variations of the two parameters with curvature are observed and calculated, revealing the high spatial and index resolution of the method. The investigation is done in single-mode optical fibers at the standard operating wavelengths of 1300 and 1550nm and at radii of curvature from 5 to 11mm. At the minimum radius of curvature R=5mm, the cladding χ(3)=4.131×1015esu on the tensile side, whereas on the compressed side it is 4.601×1015esu for λ=1300nm. On the tensile side n2=1.09×1013esu, whereas on the compressed side it is 1.216×1013esu. For λ=1550nm, the cladding χ(3) and n2 on the tensile side are 3.96×1015esu and 1.055×1013esu, whereas in the compressed cladding side they are 4.435×1015esu and 1.174×1013esu, respectively. At λ=1300nm and R=5mm, the core χ(3) is given by 4.631×1015esu on the tensile side and 4.649×1015esu on the compressed side. The asymmetry in n2 is given by 1.223×1013esu on the tensile side and by 1.227×1013esu on the compressed side. With λ=1550nm, the core χ(3) asymmetry is given by 4.46×1015esu on the tensile side and by 4.477×1015esu on the compressed side. For n2 its asymmetry is provided by 1.181×1013esu on the tensile side and by 1.185×1013esu on the compressed side.
