Figure 3: Influence on the QD’s spectral features.

From: Combining in-situ lithography with 3D printed solid immersion lenses for single quantum dot spectroscopy

Figure 3

(a) Spectra of a single QD before (blue) and after (red) the fabrication of the SIL measured at X saturation. A different intensity due to enhanced light extraction is observable after the lens fabrication. Local strain effects, induced by the contraction of the SIL, are responsible for the overall spectral shift. (b) Power dependent intensity of the QD in (a) recorded after the lens fabrication.
