title: Phase sensitive parametric fiber amplifier for the 2 μm wavelength range.
abstract: A widely tunable phase sensitive parametric fiber amplifier employing a three fiber stages configuration and operating in the 2 μm wavelength region is demonstrated. Phase sensitive gain levels of 30 dB and a gain variation of 20 dB were measured for a pulsed pump by determining the conversion efficiency near 2 μm when a signal at 1.281 μm was applied. The amplifier operates in the wavelength range of 1952 nm to 2098 nm, with its bandwidth being around 0.1 nm. The bandwidth can be controlled by the fiber lengths and their dispersion properties.
