Hi Sugeet, 

In the data file, the s-parameter is defined for each frequency, then each power of different modes of the input ports. In this way the output of the model is defined based on both the electrical input and the optical input power. The text file is generated based on simulation data and write using the "write" commands. The term abs(s) means the amplitude of the s-parameter, then the angle(s) means the angle of the s-parameter (both are single value at each frequency point, defines the complex transmission of the model under that frequency). 

 

Hope this can help.
