Hi Sushank,

Calculating the beam diameter and mode measures of fibers is done very easily in OptiFiber. In OptiSystem, you can use the Encircled Flux Visualizer to find the FWHM, as well as other mode measures, by manually comparing radius to percentage of power encircled. It might even be simpler to export the data to Matlab and calculate the mode measures automatically.
