Paper Abstract

In this paper, the refractive-index profile (RIP) of single-mode fiber is reconstructed from the measured transmitted near-field (NF) intensity combined with an inverse algorithm method, which can improve the conventional NF method to avoid the troubles introduced by multiple measurements and iteration smoothing in the processing of measuring the RIP without influencing the accuracy of the results. The method used here has the advantages of convenient operation and accurate results for the characterization of single-mode optical fiber; it can also be applied to the RIP measurement of graded index fibers, single-mode planar waveguides, and channel waveguides.
