  - <jats:title>Abstract</jats:title><jats:p>Tailored nanoscale quantum light sources,
    matching the specific needs of use cases, are crucial building blocks for photonic
    quantum technologies. Several different approaches to realize solid-state quantum
    emitters with high performance have been pursued and different concepts for energy
    tuning have been established. However, the properties of the emitted photons are
    always defined by the individual quantum emitter and can therefore not be controlled
    with full flexibility. Here we introduce an all-optical nonlinear method to tailor
    and control the single photon emission. We demonstrate a laser-controlled down-conversion
    process from an excited state of a semiconductor quantum three-level system. Based
    on this concept, we realize energy tuning and polarization control of the single
    photon emission with a control-laser field. Our results mark an important step
    towards tailored single photon emission from a photonic quantum system based on
    quantum optical principles.</jats:p>@eng
