AB  - We develop a nonclassicality criterion for the interference of three delayed,but otherwise identical, light fields in a three-mode Bell interferometer. Wedo so by comparing the prediction of quantum mechanics with those of aclassical framework in which independent sources emit electric fields withrandom phases. In particular, we evaluate third-order correlations among output intensities as a function of the delays, and show how the presence of a correlation revival for small delays cannot be explained by the classical model of light. The observation of a revival is thus a nonclassicality signature, which can be achieved only by sources with a photon-number statistics that is highly sub-Poissonian. Our analysis provides strong evidence for the nonclassicality of the experiment discussed in [Menssen et al., PRL, 118, 153603 (2017)], and shows how a collective "triad" phase affects the interference of any three or more light fields, irrespective of their quantum or classical character.
