Abstract
Starting from the semiclassical theory of light–matter interaction, we have theoretically investigated the substantial influences of two coherent driving fields on manipulating the single-photon transmission probability in the extensively studied atom-cavity-waveguide coupled system. The results strictly demonstrate that under the relatively large photon-cavity detuning and moderately strong driving fields, the single-photon transmission probability increases remarkably from the original 0 to 1 by controlling the coherent fields in the nondissipative environment, which manifests the manipulation of the coherent fields as a sort of highly controllable external tool to efficiently act as an experimentally available all-optical quantum switching. In contrast, the behavior independent from variation of coherent fields and characterized by the stationary transmission spectrum appears under the photon-atom on-resonance condition. Similar properties can also be observed in the dissipative environment. These distinct characteristics essentially reveal some significant functionalities of coherent field control in influencing the single-photon transmission spectrum, which may have potential applications in designing efficient photonic devices.
