Influencia de la energía de exposición en el perfil de índice de una red de difracción en fibra óptica: aplicación para la discriminación de deformación y temperatura

Abstract

The resulting index profile of a uniform Fiber Bragg Grating (FBG) determines the amplitudes of its first and second diffraction order wavelengths. A controlled UV writing process can be done for optimizing the reflecting powers of both wavelengths. The optimization method and results of the simulations are reported for strain and temperature discrimination using a unique FBG transducer.
