Hello Nafis Sadik,
Thanks for reaching out to us.
For your application, the best suited tool will be OptiSystem. I encourage you to download a 30 day free trial from our website. This will install the examples on your PC. Once you have OptiSystem installed, you can look at the example “XOR-Gate.osd” which can be found at the directory: C:\Users\USERNAME\Documents\OptiSystem 22.0 Samples\Optical amplifiers\Semiconductor optical amplifiers\
This can be a good starting point for you. Feel free to have a look at the other set of examples, as well as wide range of components available in the OptiSystem component library.
I hope this helps?
Let us know if you have any further questions?
Warm Regards,
Saurabh Bedi.
