Demonstration of an All-Fiber Broadband Optical Parametric Amplifier at 1 \mu m

In this paper, an optical parametric amplifier and wavelength converter in an all-fiber optical configuration is experimentally demonstrated for photonic applications in the 1 μm band. This is achieved by using a microstructured fiber which provides anomalous dispersion at 1 μm and an LiNbO 3 electro-optic intensity modulator specially designed at this operating wavelength for generating pump pulses. A gain of greater than 30 dB together with highly efficient wavelength conversion is obtained at 1053 nm. The gain bandwidth and gain-power efficiency are also investigated. Experimental results agree well with the theory of parametric amplification including Raman scattering.
