Quantum-light sources based on semiconductor quantum dots (QDs) play an important role in future development of quantum information science. For practical applications it is crucial, to efficiently couple the emission of the respective quantum emitters to a single-mode optical fiber. This coupling efficiency is largly determined by the far-field emission of the emitter.

In this work, we investigate the far-field emission characteristics of QD-based quantum light sources using Fourier imaging. The experimntal setup is introduced and exploited to measure the far-field of deterministically fabricated single-QD microlenses. These measurements and their comparison to simulations enables us to optimize the lens designs and verify theoretical simulations.
