Numerical analysis of a DFB fiber laser sensor

This paper is pointing to numerical simulation of various aspects of distributed feedback fiber laser sensors and their applications mainly in the field of the aeronautical applications. The developed numerical analysis has the aim of a better understanding of DFB-FL itself and of its interaction with environment in order to be operated as a sensor. Numerical analysis concentrates both on the FEM and phenomenological methods. Keywords— FBG, DFB-FL, DBR-FL, sensor, COMSOL.
