Non-inverse dynamics of a quantum emitter coupled to an anisotropic metasurface

Anisotropic nanophotonic structures can couple the levels of a quantum emitter through the quantum interference effects. In this paper we study the coupling of quantum emitters excited states by means of the anisotropic metasurface modes. We point out a novel degree of freedom in controlling the temporal dynamics and spectral profiles of the quantum emitters: namely, we show that a combination of the metasurface anisotropy and tilt of the emitter quantization axis with respect to the metasurface normal results in non-symmetric dynamics between the transitions of electrons from left-circular state to the right-circular states and the inverse process. Our findings give additional mechanism for control over the light emission by quantum systems and, vice versa, can be utilized for probing the active transitions of an emitter.
