Delay Interferometer

[INTAZAR Mehdi BALOCH]

Can anyone please guide me about function of Delay interferometer in Optisys. I am using OCS technique to separate Side bands of carrier generated by Laser. Using 10Ghz Sine generator, interferometer operates correctly and separates both sides bands, but when i use 20Ghs in sine generator to increase spacing between sidebands, interferometer doesn’t separate side bands on output 1. Your help will be highly appreciated. Thanx

Have you tried to play around Delay time? you can send me your project to check with you if delay did not help!

thanks

Dear Mohamed Abouseif,
I am attaching OSD file of my project. In this simulation i have set sine generator frequency to 10Ghz which produces side bands at 193.08 and 193.12Ghz.
And then delay interferometer separates both side bands accurately.
But when i change sine generator frequency to 20ghz to increase spacing between side bands, then interferometer does not seperates side bands accurately.
Please help me resolving this issue.
i have sent u file with 10ghz parameters. please change to 20ghz to see the error.

Regards,
Intazar
