“…For example, although FOPAs benefit from an ultrafast nonlinear response of silica, they also suffer from it because any fluctuations in the pump power are transferred to the signal and idler fields. As a result, noise in FOPAs is dominated by transfer of relative intensity noise (RIN) associated with the pump laser [3], [36]- [38]. Moreover, since the pump beam is typically amplified using one or two erbium-doped fiber amplifiers (EDFAs) to achieve high powers necessary for pumping an FOPA, amplified spontaneous emission (ASE) from EDFAs can degrade the FOPA considerably.…”

“…The effect of the pump noise on converted signals will be another determining factor for the system performance of the band converter. Previously, the noise figure of parametric amplifiers has been calculated for different fiber types and optimum fiber length has been proposed for dispersion shifted fibers [32], [33]. To enumerate the performance degradation, relative intensity noise (RIN) degradation along the conversion band during the wavelength conversion process is calculated analytically.…”

By using a loop configuration formed by a polarization beam splitter, we experimentally demonstrate that the existing wavelength-division multiplexing (WDM) sources in-band can be wavelength converted to the-band with low polarization sensitivity and low crosstalk. Using a fiber parametric amplifier as a band converter, we achieve experimentally 0.65-dB polarization sensitivity and 4.7-dB conversion efficiency over 30-nm conversion bandwidth in 315 m of fiber. Compared to the conventional straight fiber wavelength conversion scheme, a more than 2-dB improvement in polarization sensitivity is measured. In addition to the polarization insensitivity, channel crosstalk is measured to be 27 dB in 315 m of high nonlinearity fiber. In a detailed experimental study, the pattern of crosstalk in longer fiber lengths and the coupling between the polarization sensitivity and crosstalk are measured. For example, with a 430-m fiber length, we measure the degradation in polarization sensitivity to be 4 dB for 12-dB increased signal power. The experimental results are also confirmed by theoretical calculations. Moreover, in a 32 channels systems simulation, the signal-to-noise ratio (SNR) of the converted signals after 800-km propagation is calculated to be only 0.8-dB degraded compared to using laser diodes with the same initial SNR values. Furthermore, we calculate the effect of pump noise and show that the relative intensity noise of the pump is transferred to the converted signals with an additional 8-dB/Hz degradation.
