Gain and wavelength dependence of the noise-figure in fiber optical parametric amplification

Artikel i vetenskaplig tidskrift, 2006

We measure, for the first time, the wavelength resolved electrical noise figure (NF) of a fiber-optical parametric amplifier and find excellent agreement with theoretical predictions. We furthermore measure the NF in the exponential gain regime at high gain and quantify the gain dependence of the NF as well as its spectral dependence
