Figure 6: All-optical switching of Fano line shapes.
From: Fano resonances and all-optical switching in a resonantly coupled plasmonic–atomic system
(a) Experimental setup. (b) 85Rb-relevant transitions of the D1 and D2 manifolds (not to scale). (c) Illustration of three different pump scenarios. (d) Probe transmission as function of probe detuning for the three different pump scenarios described in c, through the plasmonic–atomic device. (e) Probe transmission through the reference cell. In both panels (d,e), the green line represents the case where the pump beam is tuned far from resonance, the blue line represents the pump beam tuned to the F=2 to F′ manifold, and the red lines represent tuning the pump to F=3 to F′ manifold.
