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. article_type: original author: - first_name: Sergey S. full_name: Kruk, Sergey S. last_name: Kruk - first_name: Wenlong full_name: Gao, Wenlong last_name: Gao - first_name: Duk-Yong full_name: Choi, Duk-Yong last_name: Choi - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 - first_name: Shuang full_name: Zhang, Shuang last_name: Zhang - first_name: Yuri full_name: Kivshar, Yuri last_name: Kivshar citation: ama: Kruk SS, Gao W, Choi D-Y, Zentgraf T, Zhang S, Kivshar Y.

Owing to huge band offsets, the structures offer resonant transitions in the telecom window around 1.55 µm. 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. While the second harmonic is originally radiated only into the plane of the quantum wells, a proper geometrical arrangement of the plasmonic elements permits the redirection of the second-harmonic light to free-space radiation, which is emitted perpendicular to the surface. article_number: '2134' article_type: original author: - first_name: Jan full_name: Mundry, Jan last_name: Mundry - first_name: Florian full_name: Spreyer, Florian last_name: Spreyer - first_name: Valentin full_name: Jmerik, Valentin last_name: Jmerik - first_name: Sergey full_name: Ivanov, Sergey last_name: Ivanov - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 - first_name: Markus full_name: Betz, Markus last_name: Betz citation: ama: Mundry J, Spreyer F, Jmerik V, Ivanov S, Zentgraf T, Betz M.

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].

Despite the strong inhomogeneity of the electron g factor, the spectral spread of optical transitions, and the broad distribution of nuclear spin fluctuations, we are able to push the whole ensemble of excited spins into a single Larmor precession mode that is commensurate with the laser repetition frequency. Furthermore, we demonstrate that an optical detuning of the pump pulses from the probed optical transitions induces a directed dynamic nuclear polarization and leads to a discretization of the total magnetic field acting on the electron ensemble. Finally, we show that the highly periodic optical excitation can be used as universal tool for strongly reducing the nuclear spin fluctuations and preparation of a robust nuclear environment for subsequent manipulation of the electron spins, also at varying operation frequencies. author: - first_name: E. full_name: Evers, E. last_name: Evers - first_name: N.

Recently, it was shown that TPhCs based on weak topology with a dislocation inherit this robustness and further host topologically protected lower-dimensional localized modes. 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. article_number: eabl3903 article_type: original author: - first_name: Jinlong full_name: Lu, Jinlong last_name: Lu - first_name: Konstantin G. full_name: Wirth, Konstantin G. last_name: Wirth - first_name: Wenlong full_name: Gao, Wenlong last_name: Gao - first_name: Andreas full_name: Heßler, Andreas last_name: Heßler - first_name: Basudeb full_name: Sain, Basudeb last_name: Sain - first_name: Thomas full_name: Taubner, Thomas last_name: Taubner - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 citation: ama: Lu J, Wirth KG, Gao W, et al.

Reflectance and transmittance can be easily configured by selecting the trench width. At sufficiently high angles of incidence, the devices are lossless, apart from material attenuation and scattering due to surface roughness. We numerically simulate a series of devices within the full 0-to-1-range of splitting ratios, for semi-guided plane wave incidence as well as for excitation by focused Gaussian wave bundles. Straightforward cascading of the trenches leads to concepts for 1×M-power dividers and a polarization beam splitter. author: - first_name: Manfred full_name: Hammer, Manfred id: '48077' last_name: Hammer orcid: 0000-0002-6331-9348 - first_name: Lena full_name: Ebers, Lena id: '40428' last_name: Ebers - first_name: Jens full_name: Förstner, Jens id: '158' last_name: Förstner orcid: 0000-0001-7059-9862 citation: ama: Hammer M, Ebers L, Förstner J.

In this work, we present a dual amplitude holographic scheme based on the photon sieve principle, which is then combined with a phase hologram by utilizing the Pancharatnam–Berry phase. We demonstrate that two types of apertures, rectangular and square shapes in a gold film filled with silicon nanoantennas are sufficient to create two amplitude holograms at two different wavelengths in the visible, multiplexed with an additional phase-only hologram. 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. author: - first_name: Daniel full_name: Frese, Daniel last_name: Frese - first_name: Basudeb full_name: Sain, Basudeb last_name: Sain - first_name: Hongqiang full_name: Zhou, Hongqiang last_name: Zhou - first_name: Yongtian full_name: Wang, Yongtian last_name: Wang - first_name: Lingling full_name: Huang, Lingling last_name: Huang - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 citation: ama: Frese D, Sain B, Zhou H, Wang Y, Huang L, 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. author: - first_name: Thomas full_name: Riedl, Thomas id: '36950' last_name: Riedl - first_name: Jörg full_name: Lindner, Jörg id: '20797' last_name: Lindner citation: ama: Riedl T, Lindner J.

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. article_number: '19081' article_type: original author: - first_name: Mahdi full_name: Hajlaoui, Mahdi last_name: Hajlaoui - first_name: Stefano full_name: Ponzoni, Stefano last_name: Ponzoni - first_name: Michael full_name: Deppe, Michael last_name: Deppe - first_name: Tobias full_name: Henksmeier, Tobias last_name: Henksmeier - first_name: Donat Josef full_name: As, Donat Josef id: '14' last_name: As orcid: 0000-0003-1121-3565 - first_name: Dirk full_name: Reuter, Dirk id: '37763' last_name: Reuter - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 - first_name: Gunther full_name: Springholz, Gunther last_name: Springholz - first_name: Claus Michael full_name: Schneider, Claus Michael last_name: Schneider - first_name: Stefan full_name: Cramm, Stefan last_name: Cramm - first_name: Mirko full_name: Cinchetti, Mirko last_name: Cinchetti citation: ama: Hajlaoui M, Ponzoni S, Deppe M, et al.
