We study a single-photon band structure in a one-dimensional coupled-resonator optical waveguide that chirally couples to an array of two-level quantum emitters (QEs). The chiral interaction between the resonator mode and the QE can break the time-reversal symmetry without the magneto-optical effect and an external or synthetic magnetic field. As a result, nonreciprocal single-photon edge states, band gaps, and flat bands appear. By using such a chiral QE coupled-resonator optical waveguide…

TLDR
This work experimentally demonstrates the nonreciprocal transmission between two counterpropagating light fields with extremely low power by adopting the strong nonlinearity associated with a few atoms in a strongly coupled cavity QED system and an asymmetric cavity configuration.

The realization of nanophotonic optical isolators with high optical isolation even at ultralow light levels and low optical losses is an open problem. Here, we employ the link between the local
Atomic spin-controlled non-reciprocal Raman amplification of fibre-guided light
In a non-reciprocal optical amplifier, gain depends on whether the light propagates forwards or backwards through the device. Typically, one requires either the magneto-optical effect, a temporal

TLDR
E engineered directional photonic reservoirs could lead to the development of complex quantum networks that, for example, could simulate novel classes of quantum many-body systems.
All-optical reversible single-photon isolation at room temperature
TLDR
Two regimes are proposed and experimentally demonstrate, using electromagnetically induced transparency (EIT) or a Raman transition, for all-optical isolation with warm atoms, which are promising for simpler reconfiguration of high-speed classical and quantum information processing.
