Frequency entangled photons have potential for various quantum applications. Recently, on-chip photon-pair sources made by CMOS compatible processes have attracted attention. In this paper, we report broadband generation of photon-pairs via a spontaneous four-wave mixing process using a CMOS compatible ring resonator. We performed frequency-correlation between the signal and idler photons by frequency-resolved coincidence detection and confirmed that the signal and idler photons are correlated over 59 frequency modes, a bandwidth of 23.6 nm, which are the largest numbers achieved to date. Furthermore, we reproduced the experimentally observed joint spectral intensity from the obtained transmission spectrum of the resonator involving the information of the dispersion of the device.
