Abstract

We investigate the coherent transport of a single photon in coupled semiconductor microcavity waveguide,which can be controlled by in-plane excitons in quantum well embedded in the antinode of the electromagnetic field in one of the cavities. The reflection coefficient and transmissivity for the single photon propagating in this semiconductor waveguide are obtained. It is shown that the effect of the excitons decay plays an important role in the transport properties of the single photon in this microcavity waveguide if we refer to real systems.
