  Multi-wavelength quantum light sources, especially at telecom band, are
extremely desired in quantum information technology. Despite recent impressive
advances, such a quantum light source with high quality remains challenging.
Here we demonstrate a multi-wavelength quantum light source using a silicon
nitride micro-ring with a free spectral range of 200 GHz. The generation of
eight pairs of correlated photons is ensured in a wavelength range of 25.6 nm.
With device optimization and noise-rejecting filters, our source enables the
generation of heralded single-photons - at a rate of 62 kHz with
$g^{(2)}_{h}(0)=0.014\pm0.001$, and the generation of energy-time entangled
photons - with a visibility of $99.39\pm 0.45\%$ in the Franson interferometer.
These results, at room temperature and telecom wavelength, in a CMOS compatible
platform, represent an important step towards integrated quantum light devices
for the quantum networks.
