Transfer-Matrix Approach to Determining the Linear Response of All-Fiber Networks of Cavity-QED Systems

Nikolett Német, White, D., Kato, S. +2 more

A semiclassical model is presented for characterizing the linear response of elementary quantum-optical systems involving cavities, optical fibers, and atoms. Formulating the transmission and reflection spectra using a scattering-wave (transfer-matrix) approach, the calculations become easily scalable. To demonstrate how useful this method is, we consider the example of a simple quantum network, i.e., two cavity-QED systems connected via an optical fiber. Differences between our quasiexact transfer-matrix approach and a single-mode, linearized quantum-optical model are demonstrated for parameters relevant to recent experiments with coupled nanofiber-cavity-QED systems.A semiclassical model is presented for characterizing the linear response of elementary quantum-optical systems involving cavities, optical fibers, and atoms.

Dynamical behaviour of coupled atom-cavity systems in the single excitation limit

Ross Shillito, Nikolett Német, A. S. Parkins

We investigate the time evolution of the photon-detection probability at various output ports of an all-fiber coupled cavity-quantum-electrodynamics (cavity-QED) system. The setup consists of two atoms trapped separately in the field of two nanofiber cavities that are connected by a standard optical fiber. We find that the normal-mode picture captures well the main features of the dynamics. However, a more accurate description based on the diagonalization of a non-Hermitian Hamiltonian reveals the origin of small yet significant features in the spontaneous emission spectra.We investigate the time evolution of the photon-detection probability at various output ports of an all-fiber coupled cavity-quantum-electrodynamics (cavity-QED) system.
