In this work, we extend the proof and present a detailed derivation of Miller's rule for an equivalent quantum-mechanical anharmonic oscillator. For this purpose, the classical concept of velocity-dependent damping inherent to the Lorentz model is replaced by an adiabatic switch-on of the external electric field, which allows a unified treatment of the classical and quantum-mechanical systems using identical potentials and fields. Although the dynamics of the resulting charge oscillations, and hence the induced polarizations, deviate due to the finite zero-point motion in the quantum-mechanical framework, we find that Miller's rule is nevertheless identical in both cases up to terms of first order in the anharmonicity. With a view to practical applications, especially in the context of ab initio calculations for the optical response where adiabatically switched-on fields are widely assumed, we demonstrate that a correct treatment of finite broadening parameters is essential to avoid spurious errors that may falsely suggest a violation of Miller's rule, and we illustrate this point by means of a numerical example. article_type: original author: - first_name: Maximilian Tim full_name: Meyer, Maximilian Tim last_name: Meyer - first_name: Arno full_name: Schindlmayr, Arno id: '458' last_name: Schindlmayr orcid: 0000-0002-4855-071X citation: ama: 'Meyer MT, Schindlmayr A.

Combining these characteristics with temporal control of SNSPDs broadens their applications as in active de-latching for higher dynamic range counting or temporal filtering for pump-probe spectroscopy or LiDAR. To that end, we demonstrate active gating of an SNSPD with a minimum off-to-on rise time of 2.4 ns and a total gate length of 5.0 ns. We show how the rise time depends on the inductance of the detector in combination with the control electronics. The gate window is demonstrated to be fully and freely, electrically tunable up to 500 ns at a repetition rate of 1.0 MHz, as well as ungated, free-running operation. Control electronics to generate the gating are mounted on the 2.3 K stage of a closed-cycle sorption cryostat, while the detector is operated on the cold stage at 0.8 K. We show that the efficiency and timing jitter of the detector is not altered during the on-time of the gating window. We exploit gated operation to demonstrate a method to increase in the photon counting dynamic range by a factor 11.2, as well as temporal filtering of a strong pump in an emulated pump-probe experiment. article_number: '610' author: - first_name: Thomas full_name: Hummel, Thomas id: '83846' last_name: Hummel - first_name: Alex full_name: Widhalm, Alex last_name: Widhalm - first_name: Jan Philipp full_name: Höpker, Jan Philipp id: '33913' last_name: Höpker - first_name: Klaus full_name: Jöns, Klaus id: '85353' last_name: Jöns - first_name: Jin full_name: Chang, Jin last_name: Chang - first_name: Andreas full_name: Fognini, Andreas last_name: Fognini - first_name: Stephan full_name: Steinhauer, Stephan last_name: Steinhauer - first_name: Val full_name: Zwiller, Val last_name: Zwiller - first_name: Artur full_name: Zrenner, Artur id: '606' last_name: Zrenner orcid: 0000-0002-5190-0944 - first_name: Tim full_name: Bartley, Tim id: '49683' last_name: Bartley citation: ama: Hummel T, Widhalm A, Höpker JP, et al.

The modular approach of the model allows to optimize hardware components with respect to the entire TRX system, and fault identification with reduced computational effort.\r\nThe proposed method is validated using the first monolithically integrated photonic radar transceiver chipset and shows excellent agreement with the post layout simulation results and, including the photodiode (PD) bandwidth (BW) degradation, also with the measurements.\r\n" author: - first_name: Stephan full_name: Kruse, Stephan id: '38254' last_name: Kruse - first_name: Tobias full_name: Schwabe, Tobias id: '39217' last_name: Schwabe - first_name: Pascal full_name: Kneuper, Pascal id: '47367' last_name: Kneuper - first_name: Marc-Michael full_name: Meinecke, Marc-Michael last_name: Meinecke - first_name: Heiko G. full_name: Kurz, Heiko G. last_name: Kurz - first_name: J.

However, three-dimensional metasurfaces with the potential to provide additional light–matter manipulation flexibility attract only little interest. Here, we demonstrate a three-dimensional metasurface scheme capable of providing dual phase control through out-of-plane plasmonic resonance of L-shape antennas. Under circularly polarized excitation at a specific wavelength, the L-shape antennas with rotating orientation angle act as spatially variant three-dimensional tilted dipoles and are able to generate desire phase delay for different polarization components. Generalized Snell's law is achieved for both in-plane and out-of-plane dipole components through arranging such L-shape antennas into arrays. These three-dimensional metasurfaces suggest a route for wavefront modulation and a variety of nanophotonic applications. article_number: '141702' article_type: original author: - first_name: Tianyou full_name: Li, Tianyou last_name: Li - first_name: Yanjie full_name: Chen, Yanjie last_name: Chen - first_name: Yongtian full_name: Wang, Yongtian last_name: Wang - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 - first_name: Lingling full_name: Huang, Lingling last_name: Huang citation: ama: Li T, Chen Y, Wang Y, Zentgraf T, Huang L.

These antennas exhibit highly directive radiation patterns and our studies reveal that this nature comes from two dominant guided TE modes excited in the waveguide-like director of the antenna, in addition to the leaky modes. The optimized antennas possess a broadband nature and have a nearunity radiation efficiency at an operational wavelength of 780 nm. Compared to the previously studied plasmonic antennas for photon emission, our all-dielectric approach demonstrates a new class of highly directional, low-loss, and broadband optical antennas. author: - first_name: Henna full_name: Farheen, Henna last_name: Farheen - first_name: Lok-Yee full_name: Yan, Lok-Yee last_name: Yan - first_name: Till full_name: Leuteritz, Till last_name: Leuteritz - first_name: Siqi full_name: Qiao, Siqi last_name: Qiao - first_name: Florian full_name: Spreyer, Florian last_name: Spreyer - first_name: Christian full_name: Schlickriede, Christian last_name: Schlickriede - first_name: Viktor full_name: Quiring, Viktor last_name: Quiring - first_name: Christof full_name: Eigner, Christof last_name: Eigner - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 - first_name: Stefan full_name: Linden, Stefan last_name: Linden - first_name: Viktor full_name: Myroshnychenko, Viktor id: '46371' last_name: Myroshnychenko - first_name: Jens full_name: Förstner, Jens id: '158' last_name: Förstner orcid: 0000-0001-7059-9862 citation: ama: 'Farheen H, Yan L-Y, Leuteritz T, et al.

For specific oblique excitation by semi-guided waves at sufficiently high angles of incidence, the idealized structures do not exhibit any radiative losses, such that reflectance and transmittance for the single port mode add strictly up to one. We consider a series of symmetric, fully and partly etched finite gratings, for parameters found in integrated silicon photonics. These can act as spectral filters with a reasonably flattop response. Apodization can lead to more box shaped reflectance and transmittance spectra. Together with a narrowband Fabry–Perot filter, these configurations are characterized by reflection bands, or transmittance peaks, with widths that span three orders of magnitude. author: - first_name: Manfred full_name: Hammer, Manfred id: '48077' last_name: Hammer orcid: 0000-0002-6331-9348 - first_name: Henna full_name: Farheen, Henna last_name: Farheen - first_name: Jens full_name: Förstner, Jens id: '158' last_name: Förstner orcid: 0000-0001-7059-9862 citation: ama: Hammer M, Farheen H, Förstner J.

The four-wave mixing data reveal clear signatures of coherent biexcitons which concur with straight-forward polarization selection rules at the Γ point. The type-I samples show the well-established time-domain beating signatures in the transients as well as the corresponding spectral signatures clearly. The latter are also present in type-II samples; however, the smaller exciton and biexciton binding energies in these structures infer longer beating times which, in turn, are accompanied by faster dephasing of the type-II exciton coherences. Furthermore, the THz absorption following spectrally narrow, picosecond excitation at energies in the vicinity of the 1s exciton resonance are discussed. Here, the optical signatures yield the well-established redshifts and blueshifts for the appropriate polarization geometries in type-I quantum well samples also termed “AC Stark Effect”. The THz probe reveals intriguing spectral features which can be ascribed to coherent negative absorption following an excitation into a virtual state for an excitation below the 1s exciton resonance. Furthermore, the scattering and ionization of excitons is discussed for several excitation geometries yielding control rules for elastic and inelastic quasiparticle collisions. article_number: '1241909' author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: M. full_name: Stein, M. last_name: Stein - first_name: F. full_name: Schäfer, F. last_name: Schäfer - first_name: D. full_name: Anders, D. last_name: Anders - first_name: J.

Such anomalous currents can be generated when Terahertz fields are applied after an optical interband excitation of GaAs quantum wells. The underlying processes are investigated by numerical solutions of the semiconductor Bloch equations in the length gauge. Excitonic effects are included by treating the manybody Coulomb interaction in time-dependent Hartree-Fock approximation and additionally also carrier-phonon scattering processes are considered. The band structure and matrix elements are obtained from a 14-band k · p model within the envelope function approximation. The random phase factors of the matrix elements that appear due to the separate numerical diagonalization at each k-point are treated by applying a smooth gauge transformation. We present the macroscopic Berry curvature and anomalous current transients with and without excitonic effects. It is demonstrated that the resonant optical excitation of excitonic resonances can significantly enhance the Berry curvature and the anomalous currents. article_number: 124190G author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: C. full_name: Ngo, C. last_name: Ngo - first_name: S. full_name: Priyadarshi, S. last_name: Priyadarshi - first_name: H.

Differential absorption spectra are computed for resonant pumping at the exciton resonance and the dependence of the absorption changes on the polarization directions of the pump and probe pulses is investigated. Coherent biexcitonic many-body correlations are included in our approach up to third-order in the optical fields. Results are presented for spatially-direct type-I and spatiallyindirect type-II quantum well systems. Due to the spatial inhomogeneity, in type-II structures a finite coupling between excitons of opposite spins exists already on the Hartree-Fock level and contributes to the absorption changes for the case of opposite circularly polarized pump and probe pulses. article_number: 124190A author: - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: Alexander full_name: Trautmann, Alexander id: '38163' last_name: Trautmann - first_name: M. full_name: Stein, M. last_name: Stein - first_name: F. full_name: Schäfer, F. last_name: Schäfer - first_name: D. full_name: Anders, D. last_name: Anders - first_name: C. full_name: Ngo, C. last_name: Ngo - first_name: J.
