The fdtd code can be changed to simulate fiber optics.
You can only change the computational domain structure.

i can not open any of them please upload it

thanks

These are the files. In the program of fdtd you just change the media or the structure to fiber optics structure or pcf or any structure you want.
If you didin't succeed we can discuss this together

This is the second file
