In analogy to the original two-photon Hong-Ou-Mandel experiment [1] we investigate three-photon interference in a two dimensional 3 × 3 waveguide (three input modes and three output modes). We consider the case of three single photons being inserted into the three separate input ports. For certain parameters of the waveguide we can find a suppression of the coincidence event, so that the three photons never leave the waveguide in three different output modes. This corresponds to the Hong-Ou-Mandel effect extended to the case of three interfering photons. Similar to the Hong-Ou-Mandel experiment the output states display entanglement in their photon number, where the exact form of the states depends on the parameters of the waveguide.
