Optical fiber sensor based on a chaotic fiber ring resonator

This paper analyzes the feasibility of using a fiber-ring chaotic resonator for optical sensing. It is demonstrated that an optically-driven fiber ring resonator is sensitive to strain, attenuation and the index of refraction of the fiber. In order to recover the measurements of a chaotic sensor like the one proposed in this paper a theoretical model is required. This model is presented and discussed in the paper. It reveals the dependencies of the geometrical parameters of the strange attractor on the optical configuration of the fiber ring. Using this model, the measurement of both strain and attenuation is simulated in this work.
