  Hi Optiwave team,
  
  I want to analyze the how the beam diameter of spatial signal is degraded as correspondence to length of transmission in optiSystem? what is the procedure to plot the graph ?

  Hi,
  
  You can start with the project file and matlab file in this other discussion:
  
  https://optiwave.com/forums/topic/system-power-penalty-and-link-margin/#post-10906
  
  In the Matlab file, I calculated the effective area of the mode, which is a common modal measure in nonlinear applications. Depending on your definition of modal diameter, you will just need to change the lines that I wrote for calculating the effective area.
  
  I hope this helps!
