Abstract

We describe a widely tunable phase sensitive fiber amplifier, based on narrowband parametric amplification in dispersion shifted fiber. Using a fiber with a zero dispersion wavelength of 1549 nm and a pump wavelength in the range of 1549 nm to 1532 nm, we obtained phase sensitive amplification between 1344 nm and 1781 nm, for an overall wavelength range of 437 nm. The amplifier threshold power is 7 W, and the maximum gain is 50 dB at a pump peak power of 25 W. The variance in gain due to phase sensitivity was measured to be up to 15 dB.
