Backward Raman amplification is applied to enhance the performance of phasesensitive fiber optical parametric amplification. The gain extinction ratio and the maximum signal gain are increased by 9.2 and 18.7 dB, respectively.
We use gain-transparent SBS to defer/expedite the saturation of a fiber optical parametric amplifier by dynamically control the phase mismatch. The input signal power at saturation can be raised or reduced by ∼6 dB.
We report suppression of pump depletion and signal gain reduction in a fiber optical parametric amplifier with a backward Raman pump. The depletion and gain saturation characteristics can be controlled by tuning the Raman gain.
We investigate the gain-saturation characteristics of a dual-orthogonal-pump fiber optical parametric amplifier. Nearly uniform power transfer functions have been obtained for various input signal polarizations by adjusting the total pump power. Based on this physical behavior, we demonstrate polarization-insensitive phase-preserving amplitude regeneration of 40-Gb/s nonreturn-to-zero differential...
Amplitude regeneration of 80-Gb/s polarization-multiplexed RZ-DPSK signals has been demonstrated in an orthogonally pumped fiber optical parametric amplifier. The receiver sensitivities of the two polarization branches are improved by 3.5 and 3.3 dB.
We investigate the nonlinear crosstalk between a 10-Gb/s differential phase-shift keying (DPSK) signal and a 160-Gb/s optical time division multiplexing on-off keying (OTDM-OOK) signal in four-wave mixing (FWM) based wavelength conversion. Experimental results show that wavelength conversion of the DPSK signal is strongly susceptible to cross-phase modulation (XPM) caused by the OTDM-OOK signal. Error-free...
We study the gain saturation and polarization dependence of a dual-orthogonal-pump fiber optical parametric amplifier. Polarization-insensitive gain saturation is observed with less than 1 dB power variation. Experimental results suggest that all-optical polarization-insensitive regeneration can be achieved with the proposed configuration, which is also applicable for polarization-multiplexed signals.
