摘要
We investigate the single-photon transport problem in the system of a whispering-gallery mode microresonator chirally coupled with a two-level quantum emitter[QE].Conventionally,this chiral QE-microresonator coupling system can be studied by the master equation and the single-photon transport methods.Here,we provide a new approach,based on the transfer matrix,to assess the single-photon transmission of such a system.Furthermore,we prove that these three methods are equivalent.The corresponding relations of parameters among these approaches are precisely deduced.The transfer matrix can be extended to a multiple-resonator system interacting with two-level QEs in a chiral way.Therefore,our work may provide a convenient and intuitive form for exploring more complex chiral cavity quantum electrodynamics systems.
