Being defined by bulk properties, such boundary states are insensitive to certain types of perturbations, thus naturally enhancing robustness of photonic circuitries. Conventionally, the N-dimensional bulk modes correspond to (N – 1)-dimensional boundary states. The higher-order bulk-boundary correspondence relates N-dimensional bulk to boundary states with dimensionality reduced by more than 1. A special interest lies in miniaturization of such higher-order topological states to the nanoscale. Here, we realize nanoscale topological corner states in metasurfaces with C6-symmetric honeycomb lattices. We directly observe nanoscale topology-empowered edge and corner localizations of light and enhancement of light–matter interactions via a nonlinear imaging technique. Control of light at the nanoscale empowered by topology may facilitate miniaturization and on-chip integration of classical and quantum photonic devices."}],"doi":"10.1021/acs.nanolett.1c00449","title":"Nonlinear Imaging of Nanoscale Topological Corner States","issue":"11","volume":21,"page":"4592–4597","type":"journal_article","quality_controlled":"1","publication":"Nano Letters"},{"department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"429"}],"publication_status":"published","citation":{"mla":"Mundry, Jan, et al. “Nonlinear Metasurface Combining Telecom-Range Intersubband Transitions in GaN/AlN Quantum Wells with Resonant Plasmonic Antenna Arrays.” <i>Optical Materials Express</i>, vol. 11, no. 7, 2134, OSA, 2021, doi:<a href=\"https://doi.org/10.1364/ome.426236\">10.1364/ome.426236</a>.","bibtex":"@article{Mundry_Spreyer_Jmerik_Ivanov_Zentgraf_Betz_2021, title={Nonlinear metasurface combining telecom-range intersubband transitions in GaN/AlN quantum wells with resonant plasmonic antenna arrays}, volume={11}, DOI={<a href=\"https://doi.org/10.1364/ome.426236\">10.1364/ome.426236</a>}, number={72134}, journal={Optical Materials Express}, publisher={OSA}, author={Mundry, Jan and Spreyer, Florian and Jmerik, Valentin and Ivanov, Sergey and Zentgraf, Thomas and Betz, Markus}, year={2021} }","short":"J.

These heterostructures are functionalized with an array of plasmonic antennas featuring cross-polarized resonances at these near-infrared wavelengths and their second harmonic. This kind of nonlinear metasurface allows for substantial second-harmonic generation at normal incidence which is completely absent for an antenna array without the multi-quantum well structure underneath.

One crucial building block are\r\ntailored nanoscale integratable quantum light sources, matching the specific\r\nneeds of use-cases. Several different approaches to realize solid-state quantum\r\nemitters [2] with high performance [3] have been pursued. However, the\r\nproperties of the emitted single photons are always defined by the individual\r\nquantum light source and despite numerous quantum emitter tuning\r\ntechniques [4-7], scalability is still a major challenge. Here we show an\r\nemitter-independent method to tailor and control the properties of the single\r\nphoton emission. We demonstrate a laser-controlled down-conversion process from\r\nan excited state of a quantum three-level system [8]. Starting from a biexciton\r\nstate, a tunable control laser field defines a virtual state in a stimulated\r\nprocess. From there, spontaneous emission to the ground state leads to\r\noptically controlled single photon emission. Based on this concept, we\r\ndemonstrate energy tuning of the single photon emission with a control laser\r\nfield. The nature of the involved quantum states furthermore provides a unique\r\nbasis for the future control of polarization and bandwidth, as predicted by\r\ntheory [9,10].

However, TPhCs with weak topology at optical frequencies have not been demonstrated so far. Here, we use scattering-type scanning near-field optical microscopy to verify mid-bandgap zero-dimensional light localization close to 100 THz in a TPhC with nontrivial Zak phase and an edge dislocation. We show that because of the weak topology, differently extended dislocation centers induce similarly strong light localization. The experimental results are supported by full-field simulations. Along with the underlying fundamental physics, our results lay a foundation for the application of TPhCs based on weak topology in active topological nanophotonics, and nonlinear and quantum optic integrated devices because of their strong and robust light localization.","lang":"eng"}],"volume":7,"article_number":"eabl3903","issue":"49","publication":"Science Advances","ddc":["530"],"quality_controlled":"1","type":"journal_article"},{"oa":"1","user_id":"477","keyword":["tet_topic_waveguide"],"title":"Configurable lossless broadband beam splitters for semi-guided waves in integrated silicon photonics","file":[{"file_name":"2021-11 Hammer - OSA Continuum - Trenches.pdf","file_size":6618403,"creator":"fossie","date_created":"2021-11-30T20:07:53Z","file_id":"28197","content_type":"application/pdf","access_level":"open_access","relation":"main_file","date_updated":"2021-11-30T20:19:15Z"}],"project":[{"name":"TRR 142","_id":"53"},{"name":"TRR 142 - Project Area C","_id":"56"}],"doi":"10.1364/osac.437549","has_accepted_license":"1","abstract":[{"lang":"eng","text":"We show that narrow trenches in a high-contrast silicon-photonics slab can act as lossless power dividers for semi-guided waves.

The nanoantennas are tailored to adjust the spectral transmittance of the apertures, enabling the wavelength sensitivity. The phase-only hologram is implemented by utilizing the anisotropic rectangular structure. Interestingly, such three holograms have quantitative mathematical correlations with each other. Thus, the flexibility of polarization and wavelength channels can be utilized with custom-tailored features to achieve such amplitude and phase holography simultaneously without sacrificing any space-bandwidth product. The present scheme has the potential to store different pieces of information which can be displayed separately by switching the wavelength or the polarization state of the reading light beam.","lang":"eng"}],"doi":"10.1515/nanoph-2021-0440","title":"A wavelength and polarization selective photon sieve for holographic applications","user_id":"30525","oa":"1","main_file_link":[{"url":"https://www.degruyter.com/document/doi/10.1515/nanoph-2021-0440/html","open_access":"1"}],"type":"journal_article","quality_controlled":"1","publication":"Nanophotonics","issue":"18","page":"4543-4550","volume":10,"intvolume":"        10","author":[{"last_name":"Frese","first_name":"Daniel","full_name":"Frese, Daniel"},{"full_name":"Sain, Basudeb","first_name":"Basudeb","last_name":"Sain"},{"last_name":"Zhou","first_name":"Hongqiang","full_name":"Zhou, Hongqiang"},{"last_name":"Wang","first_name":"Yongtian","full_name":"Wang, Yongtian"},{"last_name":"Huang","first_name":"Lingling","full_name":"Huang, Lingling"},{"first_name":"Thomas","full_name":"Zentgraf, Thomas","last_name":"Zentgraf","id":"30525","orcid":"0000-0002-8662-1101"}],"department":[{"_id":"15"},{"_id":"230"},{"_id":"289"}],"citation":{"apa":"Frese, D., Sain, B., Zhou, H., Wang, Y., Huang, L., &#38; Zentgraf, T.

In the present study, an automated analysis of scanning electron microscopy (SEM) images is described, which enables the recognition of the individual nanospheres in densely packed monolayers in order to perform a statistical quantification of the sphere size, mask opening size, and sphere-sphere separation distributions. Search algorithms based on Fourier transformation, cross-correlation, multiple-angle intensity profiling, and sphere edge point detection techniques allow for a sphere detection efficiency of at least 99.8%, even in the case of considerable sphere size variations. While the sphere positions and diameters are determined by fitting circles to the spheres edge points, the openings between sphere triples are detected by intensity thresholding. For the analyzed polystyrene sphere monolayers with sphere sizes between 220 and 600 nm and a diameter spread of around 3% coefficients of variation of 6.8–8.1% for the opening size are found. By correlating the mentioned size distributions, it is shown that, in this case, the dominant contribution to the opening size variation stems from nanometer-scale positional variations of the spheres.</jats:p>"}],"title":"Automated SEM Image Analysis of the Sphere Diameter, Sphere-Sphere Separation, and Opening Size Distributions of Nanosphere Lithography Masks","issue":"1","volume":28,"page":"185-195","type":"journal_article","publication":"Microscopy and Microanalysis","department":[{"_id":"15"},{"_id":"230"}],"publication_status":"published","citation":{"bibtex":"@article{Riedl_Lindner_2021, title={Automated SEM Image Analysis of the Sphere Diameter, Sphere-Sphere Separation, and Opening Size Distributions of Nanosphere Lithography Masks}, volume={28}, DOI={<a href=\"https://doi.org/10.1017/s1431927621013866\">10.1017/s1431927621013866</a>}, number={1}, journal={Microscopy and Microanalysis}, publisher={Cambridge University Press (CUP)}, author={Riedl, Thomas and Lindner, Jörg}, year={2021}, pages={185–195} }","mla":"Riedl, Thomas, and Jörg Lindner. “Automated SEM Image Analysis of the Sphere Diameter, Sphere-Sphere Separation, and Opening Size Distributions of Nanosphere Lithography Masks.” <i>Microscopy and Microanalysis</i>, vol. 28, no. 1, Cambridge University Press (CUP), 2021, pp. 185–95, doi:<a href=\"https://doi.org/10.1017/s1431927621013866\">10.1017/s1431927621013866</a>.","short":"T.

Exploiting their potential for further improvement and development requires a fundamental understanding of their electronic structure. So far, the most commonly used experimental techniques for this purpose have been all-optical spectroscopy methods that, however, are generally averaging in momentum space. Additional information can be gained by angle-resolved photoelectron spectroscopy (ARPES), which measures the electronic structure with momentum resolution. Here we report on the use of extremely low-energy ARPES (photon energy ~ 7 eV) to increase depth sensitivity and access buried QW states, located at 3 nm and 6 nm below the surface of cubic-GaN/AlN and GaAs/AlGaAs heterostructures, respectively. We find that the QW states in cubic-GaN/AlN can indeed be observed, but not their energy dispersion, because of the high surface roughness. The GaAs/AlGaAs QW states, on the other hand, are buried too deep to be detected by extremely low-energy ARPES. Since the sample surface is much flatter, the ARPES spectra of the GaAs/AlGaAs show distinct features in momentum space, which can be reconducted to the band structure of the topmost surface layer of the QW structure. Our results provide important information about the samples’ properties required to perform extremely low-energy ARPES experiments on electronic states buried in semiconductor heterostructures.</jats:p>","lang":"eng"}],"doi":"10.1038/s41598-021-98569-6","user_id":"14931","oa":"1","main_file_link":[{"url":"https://www.nature.com/articles/s41598-021-98569-6","open_access":"1"}],"quality_controlled":"1","publication":"Scientific Reports","type":"journal_article","volume":11,"article_number":"19081","article_type":"original","author":[{"last_name":"Hajlaoui","first_name":"Mahdi","full_name":"Hajlaoui, Mahdi"},{"full_name":"Ponzoni, Stefano","first_name":"Stefano","last_name":"Ponzoni"},{"first_name":"Michael","full_name":"Deppe, Michael","last_name":"Deppe"},{"last_name":"Henksmeier","first_name":"Tobias","full_name":"Henksmeier, Tobias"},{"id":"14","last_name":"As","first_name":"Donat Josef","full_name":"As, Donat Josef","orcid":"0000-0003-1121-3565"},{"id":"37763","last_name":"Reuter","full_name":"Reuter, Dirk","first_name":"Dirk"},{"orcid":"0000-0002-8662-1101","last_name":"Zentgraf","id":"30525","full_name":"Zentgraf, Thomas","first_name":"Thomas"},{"last_name":"Springholz","first_name":"Gunther","full_name":"Springholz, Gunther"},{"full_name":"Schneider, Claus Michael","first_name":"Claus Michael","last_name":"Schneider"},{"first_name":"Stefan","full_name":"Cramm, Stefan","last_name":"Cramm"},{"last_name":"Cinchetti","first_name":"Mirko","full_name":"Cinchetti, Mirko"}],"intvolume":"        11","citation":{"short":"M.

The 1D<br> system is chosen for simplicity in both the analytical and the numerical treatment and paves the way for the description of 2D structures in the future.
