- Abstract summary: Future quantum technology relies crucially on building quantum networks with high fidelity.
To achieve this goal, it is of utmost importance to connect single quantum systems in a way such that their emitted single-photons overlap with the highest possible degree of coherence.
Here we present an advanced manufacturing approach to accomplish this task: we combine 3D printed complex micro-optics such as hemispherical and Weierstrass solid immersion lenses.

- Abstract: Future quantum technology relies crucially on building quantum networks with
high fidelity. To achieve this challenging goal, it is of utmost importance to
connect single quantum systems in a way such that their emitted single-photons
overlap with the highest possible degree of coherence. This requires perfect
mode overlap of the emitted light of different emitters, which necessitates the
use of single mode fibers. Here we present an advanced manufacturing approach
to accomplish this task: we combine 3D printed complex micro-optics such as
hemispherical and Weierstrass solid immersion lenses as well as total internal
reflection solid immersion lenses on top of single InAs quantum dots with 3D
printed optics on single mode fibers and compare their key features.
Interestingly, the use of hemispherical solid immersion lenses further
increases the localization accuracy of the emitters to below 1 nm when
acquiring micro-photoluminescence maps. The system can be joined together and
permanently fixed. This integrated system can be cooled by dipping into liquid
helium, by a Stirling cryocooler or by a closed-cycle helium cryostat without
the necessity for optical windows, as all access is through the integrated
single mode fiber. We identify the ideal optical designs and present
experiments that prove excellent high-rate single-photon emission by
high-contrast Hanbury Brown and Twiss experiments.
