Figure 7
Coupling of emitters to the plasmonic slot mode.
(a) Purcell factor P of the plasmonic slot-stripe waveguide for three linearly independent orientations of the emitters’ dipoles calculated with equation 230. A dipole orientation along x features high P’s in the entire slot. (b) Purcell factor P (blue) and the normalized total decay rate Γtot/Γ0 (green) for an emitter’s dipole oriented along x, centered in the slot and scanned along y. (c) Corresponding β-factor (blue) and - for comparison with Chang et al.4 - the ‘effective Purcell factor’ Peff = β(1 − β) (green) also as a scan along y.
