Noise figure (NF) of the simulation of a hybrid multi-doped PbSe Quantum Dot (QD)/Multi-pumped Raman fiber amplifier for
several commercial Raman fibers, which would present a highly tunable optical amplifier are presented. The NF
dependence on the Raman fiber length and pumping power, the PbSe QD fiber length, and pumping power are studied and
analyzed. Our results are presented graphically and show an increase in the NF with increasing the Raman fiber length and
pumping power, however, the NF decreases at higher wavelengths with increasing PbSe QD fiber length and pumping
power. Curves for different Raman lengths all converge to a value around 3.3 dB with increasing signal wavelength, this is
also observed for different Raman fiber lengths curves. A QD fiber of length 20 cm with 300 mW pumping power decreases
the NF of the Raman only fiber by around 6.0 dB, the same decrease in NF is also observed by a 150 mW pumped QD fiber
with a 44 cm length.
