abstract:
- lang: eng
  text: "Photonic quantum technologies [1] with applications in quantum\r\ncommunication,
    sensing as well as quantum simulation and computing, are on the\r\nverge of becoming
    commercially available. One crucial building block are\r\ntailored nanoscale integratable
    quantum light sources, matching the specific\r\nneeds of use-cases. Several different
    approaches to realize solid-state quantum\r\nemitters [2] with high performance
    [3] have been pursued. However, the\r\nproperties of the emitted single photons
    are always defined by the individual\r\nquantum light source and despite numerous
    quantum emitter tuning\r\ntechniques [4-7], scalability is still a major challenge.
    Here we show an\r\nemitter-independent method to tailor and control the properties
    of the single\r\nphoton emission. We demonstrate a laser-controlled down-conversion
    process from\r\nan excited state of a quantum three-level system [8]. Starting
    from a biexciton\r\nstate, a tunable control laser field defines a virtual state
    in a stimulated\r\nprocess. From there, spontaneous emission to the ground state
    leads to\r\noptically controlled single photon emission. Based on this concept,
    we\r\ndemonstrate energy tuning of the single photon emission with a control laser\r\nfield.
    The nature of the involved quantum states furthermore provides a unique\r\nbasis
    for the future control of polarization and bandwidth, as predicted by\r\ntheory
    [9,10]. Our demonstration marks an important step towards tailored\r\nsingle photon
    emission from a photonic quantum system based on quantum optical\r\nprinciples."

  text: 'Platform-based business models underlie the success of many of today’s largest,
    fastest-growing, and most disruptive companies. Despite the success of prominent
    examples, such as Uber and Airbnb, creating a profitable platform ecosystem presents
    a key challenge for many companies across all industries. Although research provides
    knowledge about platforms’ different value drivers (e.g., network effects), companies
    that seek to transform their current business model into a platform-based one
    lack an artifact to reduce knowledge boundaries, collaborate effectively, and
    cope with the complexities and dynamics of platform ecosystems. We address this
    challenge by developing two artifacts and combining research from variability
    modeling, business model dependencies, and system dynamics. This paper presents
    a design science research approach to develop the platform ecosystem modeling
    language and the platform ecosystem development tool that support researcher and
    practitioner by visualizing and simulating platform ecosystems. '

  text: Gaussian-beam-like bundles of semi-guided waves propagating in a dielectric
    slab can excite modes with high-order optical angular momentum supported by a
    circular fiber. We consider a multimode step-index fiber with a high-index coating,
    where the waves in the slab are evanescently coupled to the modes of the fiber.
    Conditions for effective resonant interaction are identified. Based on a hybrid
    analytical–numerical coupled mode model, our simulations predict that substantial
    fractions of the input power can be focused into waves with specific orbital angular
    momentum, of excellent purity, with a clear distinction between degenerate modes
    with opposite vorticity.

  text: <jats:title>Abstract</jats:title><jats:p>The coherent electron spin dynamics
    of an ensemble of singly charged (In,Ga)As/GaAs quantum dots in a transverse magnetic
    field is driven by periodic optical excitation at 1 GHz repetition frequency.
    Despite the strong inhomogeneity of the electron <jats:italic>g</jats:italic>
    factor, the spectral spread of optical transitions, and the broad distribution
    of nuclear spin fluctuations, we are able to push the whole ensemble of excited
    spins into a single Larmor precession mode that is commensurate with the laser
    repetition frequency. Furthermore, we demonstrate that an optical detuning of
    the pump pulses from the probed optical transitions induces a directed dynamic
    nuclear polarization and leads to a discretization of the total magnetic field
    acting on the electron ensemble. Finally, we show that the highly periodic optical
    excitation can be used as universal tool for strongly reducing the nuclear spin
    fluctuations and preparation of a robust nuclear environment for subsequent manipulation
    of the electron spins, also at varying operation frequencies.</jats:p>

  text: Topological photonic crystals (TPhCs) provide robust manipulation of light
    with built-in immunity to fabrication tolerances and disorder. Recently, it was
    shown that TPhCs based on weak topology with a dislocation inherit this robustness
    and further host topologically protected lower-dimensional localized modes. However,
    TPhCs with weak topology at optical frequencies have not been demonstrated so
    far. Here, we use scattering-type scanning near-field optical microscopy to verify
    mid-bandgap zero-dimensional light localization close to 100 THz in a TPhC with
    nontrivial Zak phase and an edge dislocation. We show that because of the weak
    topology, differently extended dislocation centers induce similarly strong light
    localization. The experimental results are supported by full-field simulations.
    Along with the underlying fundamental physics, our results lay a foundation for
    the application of TPhCs based on weak topology in active topological nanophotonics,
    and nonlinear and quantum optic integrated devices because of their strong and
    robust light localization.
