Abstract

We report an observation of parametric amplification with a gain greater than 30 dB in a 1.7-m microstructure fiber. It is found that there exists a peak pump power P_s. For peak pump powers less than P_s, the amplified twin (signal: longer wavelength, and idler: shorter wavelength) pulses are highly correlated, and the bandwidth of the amplified signal pulse broadens monotonically with pump power. For peak pump powers exceeding P_s, the correlation between the amplified twin pulses drops when the pump power increases, the bandwidth of the amplified signal pulse becomes narrower when the pump power increases, and the central wavelength of the amplified signal (idler) pulse shifts towards longer (shorter) wavelength, respectively, due to phase matching.
