Photon-pairs generated by spontaneous four-wave mixing (SFWM) in inhibited-coupling hollow-core photonic crystal fiber (IC-HCPCF) filled with an inert gas (Xenon) combine Raman free generation, high signal-to-noise ratio, entanglement control and integrability in the telecommunications network [1]. Furthermore, this technology proved to be a promising platform for both single photon and entangled photon-pairs sources. However, increasing the brightness of such platform is required. Recently, we demonstrated an enhancement of this photon -pairs source brightness by an order of magnitude to reach $B_{0}=30\text{kHz}$ using GHz-repetition rate femtosecond laser [2].
