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.","lang":"eng"}],"article_type":"original","date_created":"2024-03-22T08:44:39Z","status":"public","publication_status":"accepted","publication_identifier":{"issn":["0953-4075"],"eissn":["1361-6455"]},"publication":"Journal of Physics B: Atomic, Molecular and Optical Physics","department":[{"_id":"296"},{"_id":"230"},{"_id":"15"},{"_id":"170"},{"_id":"35"}],"author":[{"last_name":"Meyer","first_name":"Maximilian Tim","full_name":"Meyer, Maximilian Tim"},{"orcid":"0000-0002-4855-071X","full_name":"Schindlmayr, Arno","first_name":"Arno","id":"458","last_name":"Schindlmayr"}],"publisher":"IOP Publishing","quality_controlled":"1","doi":"10.1088/1361-6455/ad369c","date_updated":"2024-03-22T08:47:41Z","_id":"52723","language":[{"iso":"eng"}],"citation":{"ieee":"M.

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."}]},{"language":[{"iso":"eng"}],"citation":{"short":"P.R.

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","lang":"eng"}]},{"user_id":"30525","article_type":"original","abstract":[{"text":"The achievement of a flat metasurface has realized extraordinary control over light–matter interaction at the nanoscale, enabling widespread use in imaging, holography, and biophotonics. 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.","lang":"eng"}],"volume":122,"status":"public","date_created":"2023-04-06T06:01:06Z","author":[{"full_name":"Li, Tianyou","first_name":"Tianyou","last_name":"Li"},{"last_name":"Chen","full_name":"Chen, Yanjie","first_name":"Yanjie"},{"first_name":"Yongtian","full_name":"Wang, Yongtian","last_name":"Wang"},{"orcid":"0000-0002-8662-1101","full_name":"Zentgraf, Thomas","first_name":"Thomas","id":"30525","last_name":"Zentgraf"},{"first_name":"Lingling","full_name":"Huang, Lingling","last_name":"Huang"}],"quality_controlled":"1","publisher":"AIP Publishing","publication":"Applied Physics Letters","keyword":["Physics and Astronomy (miscellaneous)"],"article_number":"141702","issue":"14","intvolume":" 122","_id":"43421","citation":{"apa":"Li, T., Chen, Y., Wang, Y., Zentgraf, T., & Huang, L.

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."}],"user_id":"16199","citation":{"chicago":"Meier, Torsten, M.

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.

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."}],"volume":12419,"date_created":"2023-03-29T20:22:19Z","status":"public","publication":"Ultrafast Phenomena and Nanophotonics XXVII","publisher":"SPIE","author":[{"last_name":"Meier","id":"344","first_name":"Torsten","full_name":"Meier, Torsten","orcid":"0000-0001-8864-2072"},{"id":"38163","last_name":"Trautmann","full_name":"Trautmann, Alexander","first_name":"Alexander"},{"full_name":"Stein, M.","first_name":"M.","last_name":"Stein"},{"last_name":"Schäfer","full_name":"Schäfer, F.","first_name":"F."},{"last_name":"Anders","first_name":"D.","full_name":"Anders, D."},{"last_name":"Ngo","full_name":"Ngo, C.","first_name":"C."},{"full_name":"Steiner, J.
