The optimized antennas possess a broadband nature and have a nearunity radiation efficiency at an operational wavelength of 780 nm.

In the present work, it focuses on the generation of pairs of photons with high degrees of polarization entanglement and simultaneously high indistinguishability. It achieves this goal by selectively reducing the biexciton lifetime with an optical resonator. It demonstrates that a suitably tailored circular Bragg reflector fulfills the requirements of sufficient selective Purcell enhancement of biexciton emission paired with spectrally broad photon extraction and twofold degenerate optical modes. The in‐depth theoretical study combines (i) the optimization of realistic photonic structures solving Maxwell's equations from which model parameters are extracted as input for (ii) microscopic simulations of quantum‐dot cavity excitation dynamics with full access to photon properties. It reports non‐trivial dependencies on system parameters and use the predictive power of the combined theoretical approach to determine the optimal range of Purcell enhancement that maximizes indistinguishability and entanglement to near unity values, here specifically for the telecom C‐band at 1550 nm.","lang":"eng"}],"language":[{"iso":"eng"}],"issue":"1","year":"2023","date_created":"2025-09-12T11:11:56Z","publisher":"Wiley","title":"On‐Demand Indistinguishable and Entangled Photons Using Tailored Cavity Designs"},{"publisher":"Optica Publishing Group","date_updated":"2025-09-18T12:08:56Z","date_created":"2025-09-18T12:06:19Z","author":[{"first_name":"Christof","full_name":"Eigner, Christof","id":"13244","last_name":"Eigner","orcid":"https://orcid.org/0000-0002-5693-3083"},{"first_name":"Laura","id":"40300","full_name":"Padberg, Laura","last_name":"Padberg"},{"first_name":"Viktor","last_name":"Quiring","full_name":"Quiring, Viktor"},{"first_name":"Adriana","full_name":"Bocchini, Adriana","id":"58349","orcid":"0000-0002-2134-3075","last_name":"Bocchini"},{"orcid":"0000-0001-5718-358X","last_name":"Santandrea","full_name":"Santandrea, Matteo","id":"55095","first_name":"Matteo"},{"full_name":"Gerstmann, Uwe","id":"171","last_name":"Gerstmann","orcid":"0000-0002-4476-223X","first_name":"Uwe"},{"first_name":"Wolf Gero","orcid":"0000-0002-2717-5076","last_name":"Schmidt","full_name":"Schmidt, Wolf Gero","id":"468"},{"first_name":"Christine","id":"26263","full_name":"Silberhorn, Christine","last_name":"Silberhorn"}],"title":"Potassium Titanyl Phosphate Material Engineering Boosting Integrated Optical Source Performance","doi":"10.1364/cleo_at.2023.jw2a.57","publication_status":"published","year":"2023","citation":{"ama":"Eigner C, Padberg L, Quiring V, et al.

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."}],"publication":"Optics Express","type":"journal_article","language":[{"iso":"eng"}],"keyword":["Atomic and Molecular Physics","and Optics"],"article_number":"610","department":[{"_id":"15"},{"_id":"623"},{"_id":"230"},{"_id":"429"},{"_id":"642"}],"user_id":"48188","_id":"36471"},{"language":[{"iso":"eng"}],"article_number":"2200408","keyword":["Condensed Matter Physics","Atomic and Molecular Physics","and Optics","Electronic","Optical and Magnetic Materials"],"user_id":"16199","department":[{"_id":"15"},{"_id":"170"},{"_id":"230"},{"_id":"569"},{"_id":"429"},{"_id":"35"}],"_id":"41035","status":"public","type":"journal_article","publication":"Laser & Photonics Reviews","doi":"10.1002/lpor.202200408","title":"Nonlinear Dielectric Nanoresonators and Metasurfaces: Toward Efficient Generation of Entangled Photons","author":[{"first_name":"Polina R.","id":"60286","full_name":"Sharapova, Polina R.","last_name":"Sharapova"},{"full_name":"Kruk, Sergey S.","last_name":"Kruk","first_name":"Sergey S."},{"last_name":"Solntsev","full_name":"Solntsev, Alexander S.","first_name":"Alexander S."}],"date_created":"2023-01-30T18:24:45Z","date_updated":"2025-12-16T11:26:28Z","publisher":"Wiley","citation":{"short":"P.R.

One observes an efficient resonant interaction in cases where the common axial wavenumber of the waves in the slab matches the propagation constant of one or more modes of the rod.

We consider spherical clusters, thick layers and monolayers with realistic topologies and dimensions much larger than the wavelength of light. The maximum bulk packing density of clusters is 0.5. A numerically exact solution of the electromagnetic problem is obtained using the Discontinuous Galerkin Time Domain method and with application of high- performance computing. We show that high packing density causes light localization in such structures which makes an impact on the opposition phenomena: backscattering intensity surge and negative linear polarization feature. Diffuse multiple scattering is significantly reduced in the case of non-absorbing particles and near-field interaction results in a percolation-like light transport determined by the topology of the medium. With this the negative polarization feature caused by single scattering gets enhanced if compared to lower density samples. We also confirm coherent double scattering mechanism of negative polarization for light scattered from dense absorbing slabs. In this case convergent result for the scattering angle polarization dependency at backscattering can be obtained for a layer of just a few tens of particles if they are larger than the wavelength."}],"file":[{"file_name":"2022-09 Grynko - Book chapter on Light Scattering by Large Densely Packed Clusters of Particles.pdf","file_id":"33467","access_level":"local","file_size":1525307,"creator":"fossie","date_created":"2022-09-22T09:24:45Z","date_updated":"2022-09-22T09:24:45Z","relation":"main_file","content_type":"application/pdf"}],"publication":"Springer Series in Light Scattering - Volume 8: Light Polarization and Multiple Scattering in Turbid Media","title":"Light Scattering by Large Densely Packed Clusters of Particles","publisher":"Springer International Publishing","date_created":"2022-09-22T09:18:45Z","year":"2022"},{"language":[{"iso":"eng"}],"publication":"physica status solidi (b)","abstract":[{"lang":"eng","text":"The third‐order susceptibility of lithium niobate (LiNbO3) is calculated within a Berry‐phase formulation of the dynamical polarization based on the electronic structure obtained within density‐functional theory (DFT).

These applications require state-of-the-art engineering to reach optimized functionalities such as high directivity and radiation efficiency, low sidelobe levels, broadband and tunable capabilities, and compact design. In this work, we report on the numerical optimization of the directivity of optical traveling wave antennas made from low-loss dielectric materials using full-wave numerical simulations in conjunction with the particle swarm optimization algorithm. The antennas are composed of a reflector and a director deposited on a glass substrate, and an emitter placed in the feed gap between them serves as an internal source of excitation. In particular, we analyze antennas with rectangular- and horn-shaped directors made of either hafnium dioxide or silicon. The optimized antennas produce highly directional emissions due to the presence of two dominant guided TE modes in the director in addition to leaky modes. These guided modes dominate the far-field emission pattern and govern the direction of the main lobe emission, which predominately originates from the end facet of the director. Our work also provides a comprehensive analysis of the modes, radiation patterns, parametric influences, and bandwidths of the antennas, which highlights their robust nature."}]},{"citation":{"apa":"Alhaddad, S., Grynko, Y., Farheen, H., & Förstner, J.
