Abstract :
A novel fibre Raman amplifier configuration for reduction of double Rayleigh scattering noise along with gain flattening is proposed It is demonstrated both theoretically and experimentally that an appropriately positioned filter in a single stage amplifier significantly improves Rayleigh noise performance with minimal spontaneous noise penalty.
