Fluorescence Enhancement Factors on Optical Antennas: Enlarging the Experimental Values without Changing the Antenna Design

Figure 5

Fluorescence enhancement factor (a) and fluorescence detection rate per emitter (b) for different numerical apertures (NAs) used for collection, different quantum yield of the emitter in solution (in the absence of the antenna) and in the limit of weak excitation (blue) or fluorescence saturation (red). The antenna used here is the corrugated aperture with five grooves described in Figure 1 and calibrated in [33].
