Thank you very much for your help Ravil and shrama. I already downloaded the desired files following your helps.
I am thinking of using this tool for my PhD research. However, I am now quite confusing a little bit how deep I can monitor into optical devices in OptiSystem. I am not sure since I see many things done completely. It is great to know that the Optisystem can be integrated into Matlab, and it would be more plexibilitle for me. Do you have any documents related to this matter? I see some guides at the library but I wonder are there other documents, more deeply. Thank you very much,
By the way, can you refer me some paper which used OptiSytem for their work? It seems to me that the tool is not usually used to research.
Thank you and have a nice time,
