  I was following the example "Spontaneous four-wave mixing (SFWM) microring resonator photon source". In step 4, I had an error in the script line 17 as shown below screenshot. I am not sure how to fix the problem.

  Thank you to bring this issue to us. The "mode_area_SiN_updated" file is missing. Once found we will update the website.

  I also encountered this problem. I just downloaded a new file, but I found that the script has not been modified. This issue still occurs after running.

  Thank you for pointing out. Please do the following modification:
  1: rename file effective_mode_area.lsf to be effective_mode_area_function.lsf;
  2: open mode_area_step4.lsf ;
  2: modify the function name from " mode_area_SiN_updated" to effective_mode_area_function. eg
  #mode_area_SiN_updated;
  effective_mode_area_function;
