Abstract

This paper deals with photodetected noise processes occuring in co-propagative DRA (Distributed Raman Amplifiers) such as beat noises. We develop here numerical modelisations and experimental set-ups in order to confront theory and measurements for each excess noise source. Our measurements demonstrate that the Raman ASE process, which gives rise to the DRA "background" noise, is poissonian, in spite of a super-poissonian pumping power, and how this statistics is disturbed by pump excess noise.
