Reply To: The wavelength values are different

[Afroditi Petropoulou]

Hello,

Is the example that you are using the SWG_bandstructure.fsp and the associated SWG_analyze_bandstructure.lsf script file?

If yes, as you can see in line 31 of the script file, the w_high_res parameter is calculated using the polynomial fit calculated in line 25. The wavelength is then calculated using this w_high_res parameter.

Different results can give different fits and hence different w_high_res and wavelengths. 

Since you cannot avoid the polynomial fit, unless you create a new workflow, the easiest way to get effective index results at the same wavelengths would be probably by interpolating the data using the interp - script command. You can try to check if the data are interpolated properly.

 

Best Regards,
