Investigation of dual-pump fiber optical parametric amplifier using highly nonlinear dispersion shifted fiber

Using multi-pump Raman amplifier provides high parametric gain over wide bandwidth with low noise figure (NF). Contrary to Raman amplifiers (RA), fiber optical parametric amplifiers (FOPA) can provide high and flat parametric gain over a bandwidth of tens or hundreds of nanometers with low-noise amp...

Contrary to Raman amplifiers (RA), fiber optical parametric amplifiers (FOPA) can provide high and flat parametric gain over a bandwidth of tens or hundreds of nanometers with low-noise amplification using only 2 pumps. There are two types of FOPA: FOPA of single pump (1-P) and FOPA with dual pump (2-P). Both types of FOPA can provide adjustable gain and mid-frequency spectra, wavelength conversion, phase conjugation, pulse processing for signal processing and 0 dB noise counting. Furthermore, single pump FOPA had limited parametric gain over wide bandwidth, in addition to the difficulty to obtain an equalized power. To overcome such problem dual-pump FOPA was introduced. Performances of FOPA such as parametric gain, bandwidth, and saturation power, depend on the efficiency of the four-wave mixing (FWM) process.
