摘要

The paper discusses change in behavior of current sensor using ultra low birefringence optical fiber under induced linear birefringence due to bending stress and undesired influencing parameters. Due to bending stress, it is seen that the linear polarization of light in the fiber is not maintained and it changes to elliptical polarization. Once the ultra-low birefringence Optical Fiber is employed as a sensor, prevention or elimination of induced linear birefringence due to bending stress and external influencing parameters is very important because these induced linear birefringence alters or even quenches the desired results. Further, it renders the device unstable as this induced birefringence causes difference in phase velocities and distorts polarization. Practical experience of behavior of Ultra-low-birefringence Optical Fiber for bending stress is presented. It was noticed that linearly polarized light through the fiber loses its property of linear polarization.
