“…The large spectral non-uniformity makes it difficult to spectrally match QD with the light manipulating elements within the tuning range of the well-established spectral tuning technique 19,21 . Another class of SPS is based on QDs in nanowire [12][13][14][48][49][50] structures typically grown via the metal nanoparticle seeded vapor-liquid-solid (VLS) growth mechanism. The nanowire diameter is controlled by the seed particle diameter and in turn the QD lateral size is controlled by the nanowire diameter 48,49 .…”

“…The non-SAQD quantum dots in such nanowires have been demonstrated to be single photon sources 48,50 . Moreover, the nanowire bearing the QD can also be designed to boost the collection efficiency of the emitted photons from the QD 12,13,50 . Nevertheless, certain challenges remain to be tackled, including the incorporation of metal point defects that adversely impact the optical properties of the QDs 54 , the fluctuation of nucleation events underlying VLS growth, and variation in the seed nanoparticle sizes 55 which together make predictable control on QD vertical location and emission wavelength difficult.…”

Nanophotonic quantum information processing systems require spatially ordered, spectrally uniform single photon sources (SPSs) integrated on-chip with co-designed light manipulating elements providing emission rate enhancement, emitted photon guidance, and lossless propagation. Towards this goal, we consider systems comprising an SPS array with each SPS coupled to a dielectric building block (DBB) based multifunctional light manipulation unit (LMU). For the SPS array, we report triggered single photon emission from GaAs (001)

“…A recent approach is to create polarizationentangled photons in a [111]-grown quantum dot embedded in a nanowire [47,48], where the cylindric symmetry reduces the fine-structure splitting [49]. The nanowire shape additionally offers high brightness [50] and coherent emission [47], as well as a directional Gaussian emission profile [51].…”

(2015) ' Time-bin-entangled photons are ideal for long-distance quantum communication via optical fibers. Here we present a source where, even at high creation rates, each excitation pulse generates, at most, one time-bin-entangled pair. This is important for the accuracy and security of quantum communication. Our site-controlled quantum dot generates single polarization-entangled photon pairs, which are then converted, without loss of entanglement strength, into single time-bin-entangled photon pairs.

Coherent scatterings of surface plasmons coupled to quantun dots have attracted great attention in plasmonics. Recently, an experiment has shown that the quantum dots located nearby a nanowire can be separated not only in distance, but also an angle ϕ along the cylindrical direction. Here, by using the real-space Hamiltonian and the transfer matrix method, we analytically obtain the transmission/reflection spectra of nanowire surface plasmons coupled to quantum dots with an azimuthal angle difference. We find that the scattering spectra can show completely different features due to different positions and azimuthal angles of the quantum dots. When additionally coupling a cavity to the dots, we obtain the Fano-like line shape in the transmission and reflection spectra due to the interference between the localized and delocalized modes.
