We consider spontaneous four-wave mixing (SFWM) in a single-channel side-coupled integrated spaced sequence of resonators within a fully quantum formalism. We show that the probability of photon pair production can scale quadratically with the number of resonators, a phenomenon we call super SFWM, in analogy with super-radiant spontaneous emission. Remarkably, in this situation the spectral probability density of the generated photons is independent of the number of rings.
