We propose a frequency-tunable router of single photons with high routing efficiency,which is constructed by two waveguides mediately linked by a single-mode whispering gallery resonator with a driven three-level emitter.Quantum routing probability in the output port is obtained via the real-space Hamiltonian.By adjusting the resonator-emitter cou-pling and the drive,the desired continuous central frequencies for the resonance peaks of routing photons can be manip-ulated nearly linearly,with the assistance of Rabi splitting effect and optical Stark shift.The proposed routing system may provide potential applications in designing other frequency-modulation quantum optical devices,such as multiplexers,filters,and so on.
