Abstract
Elongation characteristics of an optical fiber loop reflectors are investigated theoretically and experimentally considering fiber birefringence of the loop. Due to the birefringence formed from elliptical deformation and/or unsymmetrical stress (for example, bending) and/or twisting, the reflectivity and elongation characteristics would have some changes. During elongating process of drawing a fused taped coupler, the transmitted power of a fiber loop reflector showed some interesting characteristics as we were twisting the fiber. Even we did not twist the fiber, due to the elliptical deformation and unsymmetrical stress, the envelope of the elongation curve displayed some unsymmetrical modulation characteristics. These characteristics were more evident when the length of the fiber was longer. Using coupled-mode theory, all these experimental results were well explained.
