Abstract
There are many techniques currently used for measuring the fundamental Mode Field Distribution (MFD) of a single-mode optical waveguide. There are also many definitions of field width which can be used for characterising the measured MFD. These definitions are key parameters for describing the propagation, and other properties of any optical waveguide. A theoretical study of the evaluation of the various field width definitions from measurement data (containing noise) is described. From this study, the relationship between both accuracy and repeatability of evaluation of the definitions of Mode Field Radius (MFR) and the measurement Signal to Noise Ratio (SNR) for the various measurement techniques has been found. Tables and graphs of data are presented which indicate the necessary measurement SNR for a required accuracy of evaluation of a desired definition of MFR.
