We theoretically and experimentally reveal that when the structural symmetry of the meta-atom is incompatible with the lattice symmetry of an array, some generalized nonlinear geometric phases appear, which offers new possibilities for harmonic generation control beyond the accessible symmetries governed by the selection rule. The underlying mechanism is attributed to the modified rotation of the effective principal axis of a dense meta-atom array, where the strong coupling among the units gives rise to a generalized linear geometric phase modulation of the pump light. Therefore, nonlinear geometric phases carried by third-harmonic emissions are the natural result of the wave-mixing process among the modes excited at the fundamental frequency. This mechanism further points out a new strategy to predict the nonlinear geometric phases delivered by the nanostructures according to their linear responses. Our design is simple and efficient and offers alternatives for the nonlinear meta-devices that are capable of flexible photon generation and manipulation."}],"language":[{"iso":"eng"}],"keyword":["Electrical and Electronic Engineering","Atomic and Molecular Physics","and Optics","Biotechnology","Electronic","Optical and Magnetic Materials"]},{"language":[{"iso":"eng"}],"keyword":["Atomic and Molecular Physics","and Optics","Statistical and Nonlinear Physics"],"publication":"Journal of the Optical Society of America B","abstract":[{"text":"The Saharan desert ant Cataglyphis bombycina is densely covered with shiny silver setae (hair-like structures).

This is achieved by characterization of their structure using light microscopy and scanning/transmission electron microscopy. How the microstructural features influence scattering is investigated wave-optically within the limits of finite-difference time-domain simulations from the ultraviolet to the mid-infrared spectral range to elucidate the optical effects beyond ray optics and effective medium theory.

The fabrication of low-loss optical waveguides, as well as high-grade periodically poled ferroelectric domain structures, requires a profound understanding of the material properties and crystal structure. In this regard, Raman spectroscopy offers the possibility to study and visualize domain structures, strain, defects, and the local stoichiometry, which are all factors impacting device performance. However, the accurate interpretation of Raman spectra and their changes with respect to extrinsic and intrinsic defects requires a thorough assignment of the Raman modes to their respective crystal features, which to date is only partly conducted based on phenomenological modelling. To address this issue, we calculated the phonon spectra of potassium titanyl phosphate and the related compounds rubidium titanyl phosphate (RbTiOPO4) and potassium titanyl arsenate (KTiOAsO4) based on density functional theory and compared them with experimental data. Overall, this allows us to assign various spectral features to eigenmodes of lattice substructures with improved detail compared to previous assignments. Nevertheless, the analysis also shows that not all features of the spectra can unambigiously be explained yet. A possible explanation might be that defects or long range fields not included in the modeling play a crucial rule for the resulting Raman spectrum. In conclusion, this work provides an improved foundation into the vibrational properties in the KTiOPO4 material family.</jats:p>"}],"status":"public","project":[{"grant_number":"231447078","_id":"53","name":"TRR 142: TRR 142 - Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"}],"_id":"54852","user_id":"16199","department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"288"},{"_id":"230"},{"_id":"429"}],"article_number":"1423","language":[{"iso":"eng"}]},{"doi":"10.3390/cryst14010005","title":"Structural and Electrochemical Properties of F-Doped RbTiOPO4 (RTP:F) Predicted from First Principles","volume":14,"author":[{"first_name":"Adriana","full_name":"Bocchini, Adriana","id":"58349","last_name":"Bocchini","orcid":"0000-0002-2134-3075"},{"first_name":"Yingjie","full_name":"Xie, Yingjie","last_name":"Xie"},{"first_name":"Wolf Gero","orcid":"0000-0002-2717-5076","last_name":"Schmidt","full_name":"Schmidt, Wolf Gero","id":"468"},{"first_name":"Uwe","id":"171","full_name":"Gerstmann, Uwe","orcid":"0000-0002-4476-223X","last_name":"Gerstmann"}],"date_created":"2024-06-24T06:21:04Z","date_updated":"2024-06-24T06:30:13Z","publisher":"MDPI AG","intvolume":"        14","citation":{"ama":"Bocchini A, Xie Y, Schmidt WG, Gerstmann U.

In this theoretical study, we characterize the structural properties of a novel material, i.e., F-doped RbTiOPO4 (RbTiPO4F, RTP:F), and discuss aspects of its electrochemical performance in Rb-ion batteries (RIBs) using density functional theory (DFT). According to our calculations, RTP:F is expected to retain the so-called KTiOPO4 (KTP)-type structure, with lattice parameters of 13.236 Å, 6.616 Å, and 10.945 Å. Due to the doping with F, the crystal features eight extra electrons per unit cell, whereby each of these electrons is trapped by one of the surrounding Ti atoms in the cell. Notably, the ground state of the system corresponds to a ferromagnetic spin configuration (i.e., S=4). The deintercalation of Rb leads to the oxidation of the Ti atoms in the cell (i.e., from Ti3+ to Ti4+) and to reduced magnetic moments. The material promises interesting electrochemical properties for the cathode: rather high average voltages above 2.8 V and modest volume shrinkages below 13% even in the fully deintercalated case are predicted.</jats:p>"}],"publication":"Crystals","type":"journal_article"},{"year":"2023","issue":"12","title":"14N Hyperfine and nuclear interactions of axial and basal NV centers in 4H-SiC: A high frequency (94 GHz) ENDOR study","publisher":"AIP Publishing","date_created":"2024-06-24T06:18:17Z","abstract":[{"lang":"eng","text":"<jats:p>The nitrogen-vacancy (NV) centers (NCVSi)− in 4H silicon carbide (SiC) constitute an ensemble of spin S = 1 solid state qubits interacting with the surrounding 14N and 29Si nuclei. As quantum applications based on a polarization transfer from the electron spin to the nuclei require the knowledge of the electron–nuclear interaction parameters, we have used high-frequency (94 GHz) electron–nuclear double resonance spectroscopy combined with first-principles density functional theory to investigate the hyperfine and nuclear quadrupole interactions of the basal and axial NV centers. We observed that the four inequivalent NV configurations (hk, kh, hh, and kk) exhibit different electron–nuclear interaction parameters, suggesting that each NV center may act as a separate optically addressable qubit. Finally, we rationalized the observed differences in terms of distinctions in the local atomic structures of the NV configurations. Thus, our results provide the basic knowledge for an extension of quantum protocols involving the 14N nuclear spin.</jats:p>"}],"publication":"Journal of Applied Physics","language":[{"iso":"eng"}],"citation":{"apa":"Murzakhanov, F.

This facilitates a dynamic control of light in a compact form factor that enables the synthesis of arbitrary complex wavefronts in the infrared spectrum. We numerically demonstrate a large-scale two-dimensional silicon-based optical phased array (OPA) composed of nanoantennas with circular gratings that are balanced in power and aligned in phase, required for producing elegant radiation patterns in the far-field. For a wavelength of 1.55 μm, we optimize two antennas for the OPA exhibiting an upward radiation efficiency as high as 90%, with almost 6.8% of optical power concentrated in the field of view. Additionally, we believe that the proposed OPAs can be easily fabricated and would have the ability to generate complex holographic images, rendering them an attractive candidate for a wide range of applications like LiDAR sensors, optical trapping, optogenetic stimulation, and augmented-reality displays.","lang":"eng"}],"file":[{"relation":"main_file","content_type":"application/pdf","file_size":3339442,"access_level":"open_access","file_id":"50013","file_name":"2ß23-12 Farheen - PNFA - Optimized, highly efficient silicon antennas for optical phased arrays.pdf","date_updated":"2023-12-21T09:34:17Z","date_created":"2023-12-21T09:34:17Z","creator":"fossie"}],"keyword":["tet_topic_opticalantenna"],"ddc":["530"],"language":[{"iso":"eng"}],"year":"2023","publisher":"Elsevier BV","date_created":"2023-12-21T09:30:03Z","title":"Optimized, Highly Efficient Silicon Antennas for Optical Phased Arrays"},{"department":[{"_id":"61"},{"_id":"230"},{"_id":"429"}],"user_id":"158","_id":"43245","project":[{"grant_number":"231447078","_id":"53","name":"TRR 142: TRR 142"},{"_id":"55","name":"TRR 142 - B: TRR 142 - Project Area B"},{"grant_number":"231447078","name":"TRR 142 - B06: TRR 142 - Subproject B06","_id":"167"}],"file_date_updated":"2023-03-31T13:14:59Z","type":"journal_article","status":"public","volume":40,"author":[{"first_name":"Manfred","orcid":"0000-0002-6331-9348","last_name":"Hammer","id":"48077","full_name":"Hammer, Manfred"},{"first_name":"Henna","last_name":"Farheen","orcid":"0000-0001-7730-3489","id":"53444","full_name":"Farheen, Henna"},{"last_name":"Förstner","orcid":"0000-0001-7059-9862","full_name":"Förstner, Jens","id":"158","first_name":"Jens"}],"oa":"1","date_updated":"2024-07-22T07:44:38Z","doi":"10.1364/josab.485725","has_accepted_license":"1","publication_identifier":{"issn":["0740-3224","1520-8540"]},"publication_status":"published","intvolume":"        40","page":"862","citation":{"short":"M.

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."}],"date_created":"2023-03-31T13:04:43Z","publisher":"Optica Publishing Group","title":"How to suppress radiative losses in high-contrast integrated Bragg gratings","issue":"4","year":"2023"},{"publication":"Integrated Optics: Devices, Materials, and Technologies XXVII","file":[{"file_size":1747396,"access_level":"request","file_name":"2023-01 Poster Photonics West Henna OPA_A0.pdf","file_id":"43055","date_updated":"2023-03-22T20:53:11Z","date_created":"2023-03-22T07:41:49Z","creator":"fossie","relation":"main_file","content_type":"application/pdf"}],"abstract":[{"lang":"eng","text":"We demonstrate a large-scale two dimensional silicon-based optical phased array (OPA) composed of nanoantennas with circular gratings that are balanced in power and aligned in phase, required for producing desired radiation patterns in the far-field.
