In recent years, miniaturized photonic circuits have been extensively studied because of their various advantages over their electronic counterparts. Waveguides that guide and bend light signals in micron-scale areas are indispensable building blocks for miniaturized photonic circuits. A single crystal nanofiber of organic molecules that functions as an “active waveguide” is a promising candidate for such waveguides.

Abstract We present that two spin defects (SDs) can be entangled through a magnon polariton mode, within the strong-coupling regime. The magnon polariton modes are provided by an antiferromagnetic (AFM) MnF2 layer, where the dispersion of the modes is characterized by the layer's thickness. The macroscopic quantum electrodynamics theory is used to describe the light-matter interactions, where the Green's functions are its core elements.
