Paper Abstract

In measurements of the mode field diameter of single-mode fibers, systematic errors can result from mathematical approximations in several published formulae, and also from the use of coarsely-spaced truncated experimental data points. These two error sources have been examined for a number of fiber types, for four different methods of determining the Petermann II definition of mode field diameter. The methods are the simple far-field scan, the variable aperture in the far field, the knife edge in the far field, and the mask in the far field. We present computational formulae and experimental conditions that keep the individual errors below 0.2%.
