  text: The monolithic growth of III–V materials directly on Si substrates provides
    a promising integration approach for passive and active silicon photonic integrated
    circuits but still faces great challenges in crystal quality due to misfit defect
    formation. Nano-ridge engineering is a new approach that enables the integration
    of III–V based devices on trench-patterned Si substrates with very high crystal
    quality. Using selective area growth, the III–V material is deposited into narrow
    trenches to reduce the dislocation defect density by aspect ratio trapping. The
    growth is continued out of the trench pattern and a box-shaped III–V nano-ridge
    is engineered by adjusting the growth parameters. A flat (001) GaAs nano-ridge
    surface enables the epitaxial integration of a common InGaAs/GaAs multi-quantum-well
    (MQW) structure as an optical gain medium to build a laser diode. In this study,
    a clear correlation is found between the photoluminescence (PL) lifetime, extracted
    from time-resolved photoluminescence (TRPL) measurements, with the InGaAs/GaAs
    nano-ridge size and defect density, which are both predefined by the nano-ridge
    related pattern trench width. Through the addition of an InGaP passivation layer,
    a MQW PL lifetime of up to 800 ps and 1000 ps is measured when pumped at 900 nm
    (only QWs were excited) and 800 nm (QWs + barrier excited), respectively. The
    addition of a bottom carrier blocking layer further increases this lifetime to
    ∼2.5ns (pumped at 800 nm), which clearly demonstrates the high crystal quality
    of the nano-ridge material. These TRPL measurements not only deliver quick and
    valuable feedback about the III–V material quality but also provide an important
    understanding for the heterostructure design and carrier confinement of the nano-ridge
    laser diode.

  text: Introducing spin-polarized carriers in semiconductor lasers reveals an alternative
    path to realize room-temperature spintronic applications, beyond the usual magnetoresistive
    effects. Through carrier recombination, the angular momentum of the spin-polarized
    carriers is transferred to photons, thus leading to the circularly polarized emitted
    light. The intuition for the operation of such spin-lasers can be obtained from
    simple bucket and harmonic oscillator models, elucidating their steady-state and
    dynamic response, respectively. These lasers extend the functionalities of spintronic
    devices and exceed the performance of conventional (spin-unpolarized) lasers,
    including an order of magnitude faster modulation frequency. Surprisingly, this
    ultrafast operation relies on a short carrier spin relaxation time and a large
    anisotropy of the refractive index, both viewed as detrimental in spintronics
    and conventional lasers. Spin-lasers provide a platform to test novel concepts
    in spin devices and offer progress connected to the advances in more traditional
    areas of spintronics.

  text: <jats:p>In this paper, we present a confocal laser scanning holographic microscope
    for the investigation of buried structures. The multimodal system combines high
    diffraction limited resolution and high signal-to-noise-ratio with the ability
    of phase acquisition. The amplitude and phase imaging capabilities of the system
    are shown on a test target. For the investigation of buried integrated semiconductor
    structures, we expand our system with an optical beam induced current modality
    that provides additional structure-sensitive contrast. We demonstrate the performance
    of the multimodal system by imaging the buried structures of a microcontroller
    through the silicon backside of its housing in reflection geometry.</jats:p>

  text: The increasingly simulation-driven design process of ultrasonic transducers
    requires several reliable parameters for the description of the material behaviour.
    Exact results can only be achieved when a single specimen is used in the identification
    process, which typically is prone to the problem of low sensitivities to certain
    material parameters and thus high uncertainties. Therefore, a custom electrode
    topology for increased sensitivity is proposed for a piezoceramic disc. The thereupon
    conducted measurements of the electric impedance can be used as a starting point
    for an inverse approach where an equivalent simulation model is used to identify
    fitting material parameters. An optimisation strategy based on a preliminary sensitivity
    analysis is presented that leads to a good agreement between measurement and simulation.
    Furthermore, the proposed measurement procedure is able to evaluate the quality
    of the simulation model. Hence, different frequency-dependent damping models are
    presented and evaluated.

  text: Although there are numerous design methodologies for the LLC resonant converter,
    they often do not consider the possibility of input voltage adjustment. In the
    proposed concept, a modular multi-level converter (MMC) is used to step-down the
    three-phase medium voltage of 10 kV, and provide up to 1 MW of pure DC power to
    the load consisting of electrolyzers for hydrogen generation. Therefore, each
    module is extended by an LLC resonant converter to adapt to the specific electrolyzers
    DC voltage range of 142...220 V and to provide galvanic isolation. In order to
    achieve a high efficiency for a wide range of load conditions, the input voltage
    of the LLC converter is adjusted between 600 V and 770 V while operating at resonance
    or close to resonance. The parameters of the 11kW LLC resonant converter with
    an integrated leakage inductance are systematically optimized to maximize the
    efficiency for all loads while achieving zero-voltage switching. For a fast estimation
    of eddy current losses, a new method is proposed, which uses a single FEM simulation
    to fit newly developed loss equations. The calculated average efficiency is 97.8%.
    The prototype of the LLC converter reaches a peak efficiency of over 98% at resonance
    at half load which is similar to the precalculated value.
