Paper Abstract

In this work we present an analysis of the birefringence effects induced by external fields on passive fibers and, on the basis of this information, we propose an explanation for some effects observed in active fibers. To modify the passive fiber birefringence we have used external forces. The photo-elastic description of the birefringence induced by simple stresses is verified for short circuit cylindrical samples of silica glass (step-index and GRIN). Phase and polarization changes of light transmitted through these samples were studied using holographic interferometry and polarimetry. Using these results, a proposal is made to understand the polarization sensitivity of EDFAs. In the case of active fibers its birefringence was altered changing its geometrical shape. The amplifying performance of an EDFA built with a helically-wound active fiber was compared with that of an EDFA built with an irregularly wound erbium fiber.
