We theoretically analyze the capability of generating broadband single-photon states in photonic crystal fibers (PCF) formed by spontaneous four-wave mixing (SFWM) using femtosecond laser pulses. The design of PCF structures with the flat dispersion profile is proposed. The characteristics of the correlated photon pairs with a broadband spectrum and low spectral correlation for these structures are calculated.
