Query: Enhancing the detection probability of single waveguided-photon by
  cavity technique   The resonant-cavity-enhanced (RCE) technique is an important approach to
increasing the detection efficiency (DE) of typical free-space coupling
photons. Here, we show that such a technique can also be utilized to increase
the detection probability (DP) of a single waveguide-coupled photon. Based on a
fully quantum mechanical theory in real space, we exactly calculated the
absorption probability of a single photon for a two-level detector next to the
waveguide. We find that the DP of the waveguide photon for the detector in a
waveguide-coupled ring cavity is significantly higher than that for the bare
detector directly coupled to the photon. Physically, the DP of the photon for
the bare detector next to the waveguide is always limited by the finite
transmission and reflection probabilities of the photon. The cavity technique
is used to store the photon and thus increase its DP. The feasibility of the
proposal with current integrated optical devices is then discussed.
