Abstract: | Influence induced by Raman effect on the noise characteristics of a depleted and lossy dual pump fiber optical parametric
amplifier (FOPA) is investigated. Taking the Raman effect into account, the modified coupled amplitude equations are firstly
built, then the influences of Raman effect on the Stokes and anti-Stokes wavelengths with different initial signal powers
are further analyzed. Besides, the effect on the FOPA gain is also shown with the same initial signal power and constant noise
figure (NF). |
