Abstract: We propose to turn two resonant distant cavities effectively into one bycoupling them via an optical fiber which is coated with two-level atomsFranson et al., Phys. Rev. A 70, 062302 2004. The purpose of the atoms isto destructively measure the evanescent electric field of the fiber on a timescale which is long compared to the time it takes a photon to travel from onecavity to the other. Moreover, the boundary conditions imposed by the setupshould support a small range of standing waves inside the fiber, including oneat the frequency of the cavities. In this way, the fiber provides an additionaldecay channel for one common cavity field mode but not for the other. If thecorresponding decay rate is sufficiently large, this mode decouples effectivelyfrom the system dynamics. A single non-local resonator mode is created.
