Figure 1: SIL fabrication and optical characterization.

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

Figure 1

(a) μ-PL intensity map (200 × 200 pixels, acqusition time around 7 min) recorded after the etching of the deterministically positioned markers: the pre-selected QD (indicated by the white arrow) is centred between the etched alignment structures. (b) Microscope picture of the printed h-SIL: the markers were used as reference for the 3D printing. (c) Sketch of the μ-PL setup. A laser diode at 658 nm is used to excite the QD. The emitted light is collected by a dichroic beam splitter and sent into a spectrometer equipped with a CCD camera and a photon counting module.
