Paper Abstract

Modal fields, propagation constant and power distribution of single-mode eccentric core optical fiber are calculated based on the weakly wave-guiding approximation. The calculation of the propagation constant and power distribution is in terms of the change of the coating refractive index and eccentric distance. It is found that the evanescent field power depends on the coating refractive index and eccentric distance. In eccentric core side coating, the higher coating refractive index, the stronger evanescent field power and the larger eccentric distance, the weaker evanescent field power. The present results will be useful for deciding the geometric structure of the fiber to achieve maximum power of the evanescent field in eccentric core side coating to enhance the sensing sensitivity.
