Thanks to suitable optimization, the source shows a large spectral brightness of 400\\,pairs of entangled photons /s/MHz for $\\rm 500\\,\\mu W$ pump power. Additionally, the resonator has been engineered so as to generate a frequency comb structure compatible with standard telecom dense wavelength division multiplexers.
