We report on the experimental characterization of a novel nonlinear liquid-filled hollow-core photonic crystal fiber for the generation of photon pairs at a telecommuni- cation wavelength through spontaneous four-wave mixing (SFWM). We show that the optimization procedure in view of this application links the choice of the nonlinear liquid to the design parameters of the fiber, and we give an example of such an optimization at telecom wavelengths. Combining the modeling of the fiber and classical charac- terization techniques at these wavelengths, we identify for the chosen fiber and liquid combination SFWM phase- matching frequency ranges with no Raman scattering noise contamination. This is a first step toward obtaining a tele- com band fibered photon-pair source with a high signal-to- noise ratio.
