Linewidth and phase noise characteristics of DFB fibre lasers

By N.Y. Voo, P. Horak, M. Ibsen and W.H. Loh


The anomalous linewidth behavior in a DFB fiber laser is investigated. It is shown that not only does the linewidth deviate drastically from the Schawlow-Townes linewidth formula by increasing with pump and laser power, but it also varies significantly with the pumping configuration used. These results have potentially important implications for the design and operation of such fiber lasers
