WebDec 23, 2004 · 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. WebThroughout this paper, we consider fiber or free-space systems that use optical amplifiers and/or nonlinear optical wavelength converters, and assume that that amplified spontaneous emission (ASE) is the dominant noise source. We follow the notation used in [1], to which the reader is referred for further details and references. 2.
