use mode selector and write the mode index that you need to select
To obtain the mode index >>>>>in spatial visualizer right click component properties ,then click Results tab then select the report
you will find all modes generated
the first column is the index and use any no. in the index in mode selector to select the required mode.
But you should generate LP modes at first using CW spatial laser and Parabolic Index MMF.
Hope this helps you

Abdallah has the right idea! Using the Mode Selector and Spatial Visualizer, this should not be too hard.

Let us know if you run into anymore trouble.
