摘要：

This paper reviews characterization techniques for few mode fibers and components. The focus is on interferometric techniques including spatial and spectral resolved imaging (S-2). Simple interferometric measurements are shown to be able to give quite comprehensive information including measurement of relative group delay. A new improved algorithm for analyzing S-2 data for the case of only two modes is presented. The effect of polarization and rotation of asymmetric modes is treated as well.
