We report on a spontaneous four-wave mixing (SFWM) based broadband correlated photon pair generation using a dispersion flattened highly-nonlinear fiber (DF-HNLF). The joint spectral intensity (JSI) data indicates photon pair generation across entire S, C, and L bands and is measured using stimulated emission tomography as well as quantum state tomography in C band. The intrinsic photon pair generation rate, after accounting for system loss, and detector dark counts, is 1 kHz at peak pump power of 70 mW.
