Hi Alistu,
I tried so many times to get the result at the electrical domain by modifying the .osd design file you uploaded in reply no 24500, I followed one more book for this topic that is “broadband optical modulators, Science, Technology and applications” the circuit I uploaded before in the main question is aproximately same as that is in the book, if you have the book you can go through the pages 469-486,Sorry to say that I donot have the soft copy of the same. there they have not mentioned about any pulse requirement for the 1st cycle. I also think that there should not be any external pulse required for triggering the MZM (or electroabsoption modulator) for the 1st cycle as it is a oscillator (point of view).
so anyone please help in this matter. Thanking you.
Regards
