Remote excitation between quantum emitters mediated by an optical Fano resonance

Remote coupling between quantum emitters is of great importance for constructing networks. Conventionally, this can be achieved via photon exchange by incorporating the in a waveguide or large cavity. However, such photonic structures suffer from low quality-factors mode volumes, limiting efficiency light–matter interaction. Here, we demonstrate remote two site-controlled semiconductor dot mediated an optical Fano resonance induced cavity modes continuum state. Unlike ordinary coupled modes, offers both spatially extended field and high local density states at emitters, enhancing This scheme allows demonstration mutual excitation dots separated space > 17 wavelengths. Our approach holds promise achieving long-distance interaction without compromising efficiency, which essential scaling up on-chip integration networks based on solid-state emitters.
