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:

      http://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!
