摘要：
An eccentric core optical fiber (ECOF) for distributed evanescent field sensing is proposed. The finite element method (FEM) is utilized to analyze characteristics of the ECOF, including the fractional power of coating and core. A strong evanescent field exits in the coating of the ECOF due to a small distance between the core and the coating. The sensitivity or resolution of this kind sensing fiber is analyzed. The sensitivity is similar to 0.25dB/RIU or resolution of 4x10(-3) in the range of 1.4-1.42. The sensing length is in the range of 16m-160m.
