Relative Intensity Noise Transfer in O-Band Bismuth Doped Fibre Amplifiers
Presenter: Daniel Elson, KDDI Research Inc.
Tu3D.5
Tuesday 17th March, 17:45–18:00
Abstract: Pump-to-signal RIN transfer is observed in forward-pumped bismuth-doped f ibre amplifiers using ytterbium lasers. Although forward pumping shows a lower apparent noise figure, RIN transfer degrades SNR, while backward pumping suppresses this effect, ensuring low-noise performance.
