Compared to regular grids, they allow resembling the computational domain with a much higher accuracy, which in turn leads to more efficient computations.<br />There exists a wealth of supporting libraries and frameworks that aid programmers with the implementation of applications working on such grids, each built on top of existing parallelization technologies. However, many approaches require the programmer to introduce a different programming paradigm into their application or provide different variants of the code. SYCL is a new programming standard providing a remedy to this dilemma by building on standard C ++17 with its so-called single-source approach: Programmers write standard C ++ code and expose parallelism using C++17 keywords. The application is<br />then transformed into a concrete implementation by the SYCL implementation. By encapsulating the OpenCL ecosystem, different SYCL implementations enable not only the programming of CPUs but also of heterogeneous platforms such as GPUs or other devices.

A combination of two bent corner systems represents a step-like structure, behaving like a Fabry-Perot interferometer, with two partial reflectors separated by the vertical height between the horizontal slabs. We numerically analyse typical high-index-contrast Si/SiO2 structures for their reflectance and transmittance properties. When increasing the curvature radius the resonant effect becomes less relevant such that full transmittance is reached with less critical conditions on the vertical distance or the incidence angle.

High transmittance levels can be observed also for these 3-D configurations depending on the width of the rib.","lang":"eng"}],"file":[{"content_type":"application/pdf","file_id":"3741","date_updated":"2018-08-01T09:30:58Z","relation":"main_file","access_level":"open_access","file_size":6193865,"file_name":"2018-07 Ebers_Hammer_Förstner_OpticsExpress_Oblique incidence of semi guided planar waves on slab waveguide steps_Rounded Edges.pdf","date_created":"2018-08-01T09:30:58Z","creator":"hclaudia"}],"date_created":"2018-08-01T09:31:03Z","keyword":["tet_topic_waveguide"],"type":"journal_article","department":[{"_id":"61"}]},{"department":[{"_id":"61"},{"_id":"230"},{"_id":"429"}],"keyword":["tet_topic_waveguides"],"type":"conference","date_created":"2018-10-02T17:11:59Z","file":[{"creator":"fossie","date_created":"2018-10-02T17:13:55Z","relation":"main_file","date_updated":"2018-10-02T17:13:55Z","file_name":"2018-09 Hammer - MMET (final draft).pdf","file_size":242956,"access_level":"closed","file_id":"4580","content_type":"application/pdf","success":1}],"abstract":[{"lang":"eng","text":"Semi-guided waves confined in dielectric slab waveguides are being considered for oblique angles of propagation. If the waves encounter a linear discontinuity of (mostly) arbitrary shape and extension, a variant of Snell's law applies, separately for each pair of incoming and outgoing modes. Depending on the effective indices involved, and on the angle of incidence, power transfer to specific outgoing waves can be allowed or forbidden. In particular, critical angles of incidence can be identified, beyond which any power transfer to non-guided waves is forbidden, i.e. all radiative losses are suppressed. In that case the input power is carried away from the discontinuity exclusively by reflected semi-guided waves in the input slab, or by semi-guided waves that are transmitted into other outgoing slab waveguides. Vectorial equations on a 2-D cross sectional domain apply. These are formally identical to the equations that govern the eigenmodes of 3-D channel waveguides. Here, however, these need to be solved not as an eigenvalue problem, but as an inhomogeneous problem with a right-hand-side that is given by the incoming semi-guided wave, and subject to transparent boundary conditions. The equations resemble a standard 2-D Helmholtz problem, with an effective permittivity in place of the actual relative permittivity. Depending on the properties of the incoming wave, including the angle of incidence, this effective permittivity can become locally negative, causing the suppression of propagating outgoing waves. A series of high-contrast example configurations are discussed, where these effects lead to - in some respects - quite surprising transmission characteristics."}],"publication":"2018 IEEE 17th International Conference on Mathematical Methods in Electromagnetic Theory (MMET)","doi":"10.1109/mmet.2018.8460455","date_updated":"2022-01-06T07:01:13Z","publication_status":"published","publication_identifier":{"isbn":["9781538654385"]},"author":[{"full_name":"Hammer, Manfred","first_name":"Manfred","last_name":"Hammer","orcid":"0000-0002-6331-9348","id":"48077"},{"id":"40428","last_name":"Ebers","first_name":"Lena","full_name":"Ebers, Lena"},{"full_name":"Hildebrandt, Andre","last_name":"Hildebrandt","first_name":"Andre"},{"id":"42456","full_name":"Alhaddad, Samer","last_name":"Alhaddad","first_name":"Samer"},{"id":"158","full_name":"Förstner, Jens","first_name":"Jens","orcid":"0000-0001-7059-9862","last_name":"Förstner"}],"title":"Oblique Semi-Guided Waves: 2-D Integrated Photonics with Negative Effective Permittivity","year":"2018","project":[{"name":"TRR 142","_id":"53"},{"name":"TRR 142 - Project Area C","_id":"56"},{"name":"TRR 142 - Subproject C5","_id":"75"}],"citation":{"short":"M.

Here, an orientation dependent polarization conversion effect is reported for light reflected from diamond‐structure‐based photonic crystals (D‐structure) inside the scales of a beetle, the weevil Entimus imperialis. When linearly polarized light propagates along its 〈100〉 directions, the D‐structure behaves analogous to a half‐wave plate in reflection but based on a different mechanism. The D‐structure rotates the polarization direction of linearly polarized light, and reflects circularly polarized light of both handednesses without changing it. This polarization effect is different from circular dichroism occurring in chiral biological photonic structures discovered before. The structural origin of this effect is symmetry breaking inside D‐structure's unit cell. This finding demonstrates that natural photonic structures can exploit multiple functionalities inherent to the design principles of their structural organization. Aiming at transferring the inherent polarization effect of the biological D‐structure to technically realizable materials, three simplified biomimetic structural models are derived and it is theoretically demonstrated that they retain the effect. Out of these structures, functioning woodpile structure prototypes are fabricated.","lang":"eng"}],"_id":"4831","publisher":"Wiley","page":"1800635","volume":6,"ddc":["530"],"user_id":"158","status":"public","has_accepted_license":"1","citation":{"mla":"Wu, Xia, et al. “Polarization Conversion Effect in Biological and Synthetic Photonic Diamond Structures.” <i>Advanced Optical Materials</i>, vol. 6, no. 24, Wiley, 2018, p. 1800635, doi:<a href=\"https://doi.org/10.1002/adom.201800635\">10.1002/adom.201800635</a>.","bibtex":"@article{Wu_Rodríguez-Gallegos_Heep_Schwind_Li_Fabritius_von Freymann_Förstner_2018, title={Polarization Conversion Effect in Biological and Synthetic Photonic Diamond Structures}, volume={6}, DOI={<a href=\"https://doi.org/10.1002/adom.201800635\">10.1002/adom.201800635</a>}, number={24}, journal={Advanced Optical Materials}, publisher={Wiley}, author={Wu, Xia and Rodríguez-Gallegos, Fernando L. and Heep, Marie-Christin and Schwind, Bertram and Li, Guixin and Fabritius, Helge-Otto and von Freymann, Georg and Förstner, Jens}, year={2018}, pages={1800635} }","ama":"Wu X, Rodríguez-Gallegos FL, Heep M-C, et al.

Despite the availability of several techniques for imaging plasmons, direct access into the symmetries of these excitations remains elusive, thus hindering progress in the development of applications. Here, we present a combination of angle-, polarization-, and space-resolved cathodoluminescence spectroscopy methods to selectively access the symmetry and degeneracy of plasmonic states in lithographically fabricated gold nanoprisms. We experimentally reveal and spatially map degenerate states of multipole plasmon modes with nanometer spatial resolution and further provide recipes for resolving optically dark and out-of-plane modes. Full-wave simulations in conjunction with a simple tight-binding model explain the complex plasmon structure in these particles and reveal intriguing mode-symmetry phenomena. Our approach introduces systematics for a comprehensive symmetry characterization of plasmonic states in high-symmetry nanostructures."}],"issue":"8","publication":"ACS Nano","type":"journal_article","keyword":["tet_topic_plasmonics"],"department":[{"_id":"61"},{"_id":"230"}],"file":[{"file_id":"4166","content_type":"application/pdf","file_name":"2018 Myroshnychenko,Nishio,Garcia de Abajo,Förstner,Yamamoto_Unveiling and Imaging Degenerate States in Plasmonic Nanoparticles with Nanometer Resolution.pdf","file_size":4463352,"access_level":"open_access","relation":"main_file","date_updated":"2018-09-03T13:54:21Z","date_created":"2018-08-28T07:45:47Z","creator":"hclaudia"}],"date_created":"2018-08-28T07:44:24Z","date_updated":"2022-01-06T07:00:27Z","publication_status":"published","intvolume":"        12","article_type":"original","year":"2018","title":"Unveiling and Imaging Degenerate States in Plasmonic Nanoparticles with Nanometer Resolution","author":[{"id":"46371","full_name":"Myroshnychenko, Viktor","last_name":"Myroshnychenko","first_name":"Viktor"},{"full_name":"Nishio, Natsuki","first_name":"Natsuki","last_name":"Nishio"},{"full_name":"García de Abajo, F.

In computational sciences, often more advanced methods are employed that promise better stability, convergence, locality and scaling. Unstructured meshes are shown to be more effective and more accurate, compared to regular grids, in representing computation domains of various shapes. Using unstructured meshes, the discontinuous Galerkin method preserves the ability to perform explicit local update operations for simulations in the time domain. In this work, we investigate FPGAs as target platform for an implementation of the nodal discontinuous Galerkin method to find time-domain solutions of Maxwell's equations in an unstructured mesh. When maximizing data reuse and fitting constant coefficients into suitably partitioned on-chip memory, high computational intensity allows us to implement and feed wide data paths with hundreds of floating point operators. By decoupling off-chip memory accesses from the computations, high memory bandwidth can be sustained, even for the irregular access pattern required by parts of the application. Using the Intel/Altera OpenCL SDK for FPGAs, we present different implementation variants for different polynomial orders of the method.

Here we propose a new method to achieve direction-tunable emission based on a compact metallic microcavity with double nanoslit. Our method combines the principles of Young’s interference and surface plasmon polaritons interference. We show that the direction of the far-field beam can be controlled over a wide range of angles by manipulating the frequency and relative phase of light arriving at the two slits, which holds promise for applications in the ultracompact optoelectronic devices."}]}]
