  The capability to embed self-assembled quantum dots (QDs) at predefined
positions in nanophotonic structures is key to the development of complex
quantum photonic architectures. Here, we demonstrate that QDs can be
deterministically positioned in nanophotonic waveguides by pre-locating QDs
relative to a global reference frame using micro-photoluminescence ($\mu$PL)
spectroscopy. After nanofabrication, $\mu$PL images reveal misalignments
between the central axis of the waveguide and the embedded QD of only
$(9\pm46$) nm and $(1\pm33$) nm, for QDs embedded in undoped and doped
membranes, respectively. A priori knowledge of the QD positions allows us to
study the spectral changes introduced by nanofabrication. We record average
spectral shifts ranging from 0.1 to 1.1 nm, indicating that the
fabrication-induced shifts can generally be compensated by electrical or
thermal tuning of the QDs. Finally, we quantify the effects of the
nanofabrication on the polarizability, the permanent dipole moment and the
emission frequency at vanishing electric field of different QD charge states,
finding that these changes are constant down to QD-surface separations of only
70 nm. Consequently, our approach deterministically integrates QDs into
nanophotonic waveguides whose light-fields contain nanoscale structure and
whose group index varies at the nanometer level.
