Dear B Das

thanks for your care.

I know how PM to IM conversion works and how UWB pulse generates but when i implements the setup in optisystems,i cannot get the required pulse shapes.I am working on it since one month but still not getting where i am making a mistake or lacking a point.My supervisor says that your setup is normal and you should get the required pulse shapes.He further asks you have to find whats the issue by yourself

Dear B Das

I have a question on SOA. Please help

It has been learnt that if AWGN/White light source is coupled with CW probe and Pump signals (Data signal) and then the cumulative signal is launched in a SOA for XPM and amplification,then the SOA is very less noise tolerant and the pulse shapes and Eye diagram badly degrades at the receiver side.Why SOA is very sensitive to noise and less immune to it?

please comment and share any written literature on this property of the SOA

regards
