From: Fano resonances and all-optical switching in a resonantly coupled plasmonic–atomic system

(a) Calculated effective imaginary index of refraction of rubidium. (b) Calculated effective real index of refraction of rubidium. (c) Calculated transmission of ‘bare’ plasmonic system around the resonance, as a function of the excitation angle (relative to plasmonic resonance angle) using a three-layer model. (d–f) Calculated transmission of the combined atomic–plasmonic system at an angle corresponding to the green, red and blue square marks in Fig. 2c, respectively.
