The working principle meanwhile gives rise to the crucial problem and challenge to protect the metasurface from dust or clean the unavoidable contaminants during daily usage. Here, taking advantage of the intelligent bioinspired surfaces which exhibit self-cleaning properties, a versatile dielectric metasurface benefiting from the obtained superhydrophilic or quasi-superhydrophobic states is shown. The design is realized by embedding the metasurface inside a large area of wettability supporting structures, which is highly efficient in fabrication, and achieves both optical and wettability functionality at the same time. The superhydrophilic state enables an enhanced optical response with water, while the quasi-superhydrophobic state imparts the fragile antennas an ability to self-clean dust contamination. Furthermore, the metasurface can be easily switched and repeated between these two wettability or functional states by appropriate treatments in a repeatable way, without degrading the optical performance. The proposed design strategy will bring new opportunities to smart metasurfaces with improved optical performance, versatility, and physical stability."}],"file":[{"success":1,"relation":"main_file","content_type":"application/pdf","file_size":2801333,"access_level":"closed","file_id":"26748","file_name":"AdvOptMat_Lu_2021.pdf","date_updated":"2021-10-25T06:42:52Z","date_created":"2021-10-25T06:42:52Z","creator":"zentgraf"}],"publication":"Advanced Optical Materials","ddc":["530"],"language":[{"iso":"eng"}],"intvolume":"        10","citation":{"bibtex":"@article{Lu_Sain_Georgi_Protte_Bartley_Zentgraf_2022, title={A Versatile Metasurface Enabling Superwettability for Self‐Cleaning and Dynamic Color Response}, volume={10}, DOI={<a href=\"https://doi.org/10.1002/adom.202101781\">10.1002/adom.202101781</a>}, number={12101781}, journal={Advanced Optical Materials}, publisher={Wiley}, author={Lu, Jinlong and Sain, Basudeb and Georgi, Philip and Protte, Maximilian and Bartley, Tim and Zentgraf, Thomas}, year={2022} }","mla":"Lu, Jinlong, et al. “A Versatile Metasurface Enabling Superwettability for Self‐Cleaning and Dynamic Color Response.” <i>Advanced Optical Materials</i>, vol. 10, no. 1, 2101781, Wiley, 2022, doi:<a href=\"https://doi.org/10.1002/adom.202101781\">10.1002/adom.202101781</a>.","short":"J.

However, plasmonic metasurfaces show some severe limitation for nonlinear frequency conversion due to the intrinsic high ohmic loss and low damage threshold of plasmonic nanostructures. Here, the nonlinear geometric‐phases associated with the third‐harmonic generation process occurring in all‐dielectric metasurfaces is studied systematically, which are composed of silicon nanofins with different in‐plane rotational symmetries. It is found that the wave coupling among different field components of the resonant fundamental field gives rise to the appearance of different nonlinear geometric‐phases of the generated third‐harmonic signals. The experimental observations of the nonlinear beam steering and nonlinear holography realized in this work by all‐dielectric geometric‐phase metasurfaces are well explained with the developed theory. This work offers a new physical picture to understand the nonlinear optical process occurring at nanoscale dielectric resonators and will help in the design of nonlinear metasurfaces with tailored phase properties.","lang":"eng"}],"publication":"Advanced Optical Materials","title":"Nonlinear Wavefront Control by Geometric-Phase Dielectric Metasurfaces: Influence of Mode Field and Rotational Symmetry","date_created":"2020-02-28T17:29:17Z","publisher":"Wiley","year":"2020","issue":"9","quality_controlled":"1"},{"article_number":"2000414","keyword":["Atomic and Molecular Physics","and Optics","Electronic","Optical and Magnetic Materials"],"language":[{"iso":"eng"}],"_id":"35869","user_id":"254","department":[{"_id":"313"}],"status":"public","type":"journal_article","publication":"Advanced Optical Materials","title":"Organic Light‐Emitting Diodes Based on a Columnar Liquid‐Crystalline Perylene Emitter","doi":"10.1002/adom.202000414","date_updated":"2023-01-24T16:54:14Z","publisher":"Wiley","author":[{"first_name":"Changmin","full_name":"Keum, Changmin","last_name":"Keum"},{"first_name":"David","last_name":"Becker","full_name":"Becker, David"},{"last_name":"Archer","full_name":"Archer, Emily","first_name":"Emily"},{"first_name":"Harald","last_name":"Bock","full_name":"Bock, Harald"},{"last_name":"Kitzerow","full_name":"Kitzerow, Heinz-Siegfried","id":"254","first_name":"Heinz-Siegfried"},{"full_name":"Gather, Malte C.","last_name":"Gather","first_name":"Malte C."},{"last_name":"Murawski","full_name":"Murawski, Caroline","first_name":"Caroline"}],"date_created":"2023-01-10T14:01:41Z","volume":8,"year":"2020","citation":{"ieee":"C.

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"}],"author":[{"first_name":"Xia","full_name":"Wu, Xia","last_name":"Wu"},{"first_name":"Fernando L.","full_name":"Rodríguez-Gallegos, Fernando L.","last_name":"Rodríguez-Gallegos"},{"first_name":"Marie-Christin","full_name":"Heep, Marie-Christin","last_name":"Heep"},{"first_name":"Bertram","last_name":"Schwind","full_name":"Schwind, Bertram"},{"last_name":"Li","full_name":"Li, Guixin","first_name":"Guixin"},{"first_name":"Helge-Otto","last_name":"Fabritius","full_name":"Fabritius, Helge-Otto"},{"full_name":"von Freymann, Georg","last_name":"von Freymann","first_name":"Georg"},{"first_name":"Jens","full_name":"Förstner, Jens","id":"158","last_name":"Förstner","orcid":"0000-0001-7059-9862"}],"volume":6,"date_updated":"2022-01-06T07:01:26Z","doi":"10.1002/adom.201800635","publication_status":"published","publication_identifier":{"issn":["2195-1071"]},"has_accepted_license":"1","citation":{"short":"X.
