Photon quantum routing is one of the key elements of the quantum information network and integrated optical devices. In this paper, we theoretically investigate the single-photon transport in an intersection coupled resonant waveguide (CRW), called the T-bulge structure, in which the $$N\hbox {th}$$ cavity of a semi-infinite CRW couples with one point of an infinite CRW via a cascaded three-level atom. By using the discrete coordinates approach, transmission and reflection amplitudes of the propagating single photon in the waveguide are analytically obtained. Two cases that a si...
