Paper Abstract

We studied changes over a polarized state of a light beam into an optical fiber, and under the influence of a magnetic field. Those results can be used as a current or magnetic optical fiber sensor. Here, the measurements are based only in intensity changes, and the experimental setup contains the minimum of optical components. We show a mathematical model to describe our setup including controllable parameters such as, the birefringence in fiber, the incident angle of the light, the current applied to a coil (the magnetic field involving the fiber), and length of the coil. The theory, simulations and experimental verification of this problem are discussed.
