Hi Dhiman,
As far as I know, Optisystem is the only Optiwave software to implement systems this way, and it is against forum rules to discuss products from other companies. Besides, using a screenshot from some software using a whole other software is not common in papers and theses. Nevertheless, I would also like to know how the schematics (which are not screenshots and look as if they were drawn) are made in papers and would be grateful if someone shares their experience.
