However, three-dimensional metasurfaces with the potential to provide additional light–matter manipulation flexibility attract only little interest. Here, we demonstrate a three-dimensional metasurface scheme capable of providing dual phase control through out-of-plane plasmonic resonance of L-shape antennas. Under circularly polarized excitation at a specific wavelength, the L-shape antennas with rotating orientation angle act as spatially variant three-dimensional tilted dipoles and are able to generate desire phase delay for different polarization components. Generalized Snell's law is achieved for both in-plane and out-of-plane dipole components through arranging such L-shape antennas into arrays. These three-dimensional metasurfaces suggest a route for wavefront modulation and a variety of nanophotonic applications."}],"user_id":"30525","citation":{"apa":"Li, T., Chen, Y., Wang, Y., Zentgraf, T., & Huang, L.

The theoretically predicted behavior of the metasurface is experimentally verified by linear and nonlinear transmission spectroscopy. Moreover, quantitative nonlinear measurements are performed, in which an absolute conversion efficiency as high as ηmax ≈ 2.8 × 10−7 a peak power intensity of 1.2 GW cm−2 is found. Compared to an unpatterned silicon film of the same thickness amplification factors of up to ~900 are demonstrated. Our results pave the way to exploiting a strong Fano-type multi-mode coupling in metasurfaces for high THG in potential applications."}],"article_type":"original","ddc":["530"],"user_id":"158","publication":"Light: Science & Applications","file_date_updated":"2023-04-21T10:03:30Z","keyword":["tet_topic_meta"],"quality_controlled":"1","author":[{"full_name":"Hähnel, David","first_name":"David","last_name":"Hähnel"},{"last_name":"Golla","first_name":"Christian","full_name":"Golla, Christian"},{"full_name":"Albert, Maximilian","first_name":"Maximilian","last_name":"Albert"},{"id":"30525","last_name":"Zentgraf","orcid":"0000-0002-8662-1101","full_name":"Zentgraf, Thomas","first_name":"Thomas"},{"last_name":"Myroshnychenko","id":"46371","first_name":"Viktor","full_name":"Myroshnychenko, Viktor"},{"id":"158","last_name":"Förstner","orcid":"0000-0001-7059-9862","full_name":"Förstner, Jens","first_name":"Jens"},{"id":"20798","last_name":"Meier","full_name":"Meier, Cedrik","orcid":"https://orcid.org/0000-0002-3787-3572","first_name":"Cedrik"}],"publisher":"Springer Nature","file":[{"access_level":"open_access","date_created":"2023-04-21T10:00:27Z","file_name":"2023-04 Hähnel - LSA - Multimode Fano THG.pdf","date_updated":"2023-04-21T10:00:27Z","content_type":"application/pdf","relation":"main_file","file_size":2088874,"file_id":"44098","creator":"fossie"},{"relation":"supplementary_material","content_type":"application/pdf","date_updated":"2023-04-21T10:03:30Z","creator":"fossie","file_id":"44099","file_size":986743,"access_level":"open_access","date_created":"2023-04-21T10:03:30Z","file_name":"2023-04 Hähnel - LSA - Multimode Fano THG (supplementary information).pdf"}],"volume":12,"date_created":"2023-04-21T09:45:07Z","status":"public","has_accepted_license":"1","date_updated":"2023-04-21T10:04:05Z","doi":"https://doi.org/10.1038/s41377-023-01134-1","oa":"1","language":[{"iso":"eng"}],"title":"A multi-mode super-fano mechanism for enhanced third harmonic generation in silicon metasurfaces","department":[{"_id":"61"},{"_id":"230"},{"_id":"429"}],"publication_status":"published","publication_identifier":{"issn":["2047-7538"]}},{"date_created":"2023-04-18T05:47:22Z","has_accepted_license":"1","status":"public","volume":23,"file":[{"file_id":"44045","creator":"zentgraf","file_size":1315966,"relation":"main_file","success":1,"content_type":"application/pdf","date_updated":"2023-04-18T05:50:19Z","file_name":"acs.nanolett.2c04980.pdf","date_created":"2023-04-18T05:50:19Z","access_level":"closed"}],"keyword":["Mechanical Engineering","Condensed Matter Physics","General Materials Science","General Chemistry","Bioengineering"],"publication":"Nano Letters","file_date_updated":"2023-04-18T05:50:19Z","author":[{"full_name":"Geromel, René","first_name":"René","last_name":"Geromel"},{"full_name":"Georgi, Philip","first_name":"Philip","last_name":"Georgi"},{"full_name":"Protte, Maximilian","first_name":"Maximilian","id":"46170","last_name":"Protte"},{"first_name":"Shiwei","full_name":"Lei, Shiwei","last_name":"Lei"},{"first_name":"Tim","full_name":"Bartley, Tim","last_name":"Bartley","id":"49683"},{"last_name":"Huang","first_name":"Lingling","full_name":"Huang, Lingling"},{"last_name":"Zentgraf","id":"30525","first_name":"Thomas","orcid":"0000-0002-8662-1101","full_name":"Zentgraf, Thomas"}],"quality_controlled":"1","publisher":"American Chemical Society (ACS)","user_id":"30525","ddc":["530"],"abstract":[{"text":"Dispersion is present in every optical setup and is often an undesired effect, especially in nonlinear-optical experiments where ultrashort laser pulses are needed.

However, these devices are only able to compensate for a part of the dispersion (second-order dispersion). Here, we present a compact pulse-shaping device that uses plasmonic metasurfaces to apply an arbitrarily designed spectral phase delay allowing for a full dispersion control. Furthermore, with specific phase encodings, this device can be used to temporally reshape the incident laser pulses into more complex pulse forms such as a double pulse. We verify the performance of our device by using an SHG-FROG measurement setup together with a retrieval algorithm to extract the dispersion that our device applies to an incident laser pulse.","lang":"eng"}],"article_type":"original","page":"3196 - 3201","year":"2023","type":"journal_article","citation":{"ama":"Geromel R, Georgi P, Protte M, et al.

PVVBs are typically generated through the superposition of perfect vortex beams, which suffer from the limited number of topological charges (TCs). Furthermore, dynamic control of PVVBs is desirable and has not been reported. We propose and experimentally demonstrate hybrid grafted perfect vector vortex beams (GPVVBs) and their dynamic control. Hybrid GPVVBs are generated through the superposition of grafted perfect vortex beams with a multifunctional metasurface. The generated hybrid GPVVBs possess spatially variant rates of polarization change due to the involvement of more TCs. Each hybrid GPVVB includes different GPVVBs in the same beam, adding more design flexibility. Moreover, these beams are dynamically controlled with a rotating half waveplate. The generated dynamic GPVVBs may find applications in the fields where dynamic control is in high demand, including optical encryption, dense data communication, and multiple particle manipulation."}],"ddc":["530"],"user_id":"30525"},{"user_id":"30525","abstract":[{"lang":"eng","text":"We present a miniaturized pulse shaping device that creates an arbitrary dispersion through the interaction of multiple metasurfaces on less than 2 mm3 volume.

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.","lang":"eng"}],"citation":{"short":"B.

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.","lang":"eng"}],"article_type":"original","user_id":"30525","ddc":["530"],"file":[{"file_size":2801333,"file_id":"26748","creator":"zentgraf","date_updated":"2021-10-25T06:42:52Z","content_type":"application/pdf","relation":"main_file","success":1,"date_created":"2021-10-25T06:42:52Z","file_name":"AdvOptMat_Lu_2021.pdf","access_level":"closed"}],"file_date_updated":"2021-10-25T06:42:52Z","publication":"Advanced Optical Materials","quality_controlled":"1","author":[{"first_name":"Jinlong","full_name":"Lu, Jinlong","last_name":"Lu"},{"full_name":"Sain, Basudeb","first_name":"Basudeb","last_name":"Sain"},{"full_name":"Georgi, Philip","first_name":"Philip","last_name":"Georgi"},{"last_name":"Protte","full_name":"Protte, Maximilian","first_name":"Maximilian"},{"id":"49683","last_name":"Bartley","full_name":"Bartley, Tim","first_name":"Tim"},{"last_name":"Zentgraf","id":"30525","first_name":"Thomas","orcid":"0000-0002-8662-1101","full_name":"Zentgraf, Thomas"}],"publisher":"Wiley","date_created":"2021-10-25T06:34:38Z","status":"public","has_accepted_license":"1","volume":10,"date_updated":"2022-02-28T08:26:45Z","oa":"1","doi":"10.1002/adom.202101781","language":[{"iso":"eng"}],"title":"A Versatile Metasurface Enabling Superwettability for Self‐Cleaning and Dynamic Color Response","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"}],"publication_identifier":{"issn":["2195-1071","2195-1071"]},"publication_status":"published"},{"abstract":[{"lang":"eng","text":"While plasmonic particles can provide optical resonances in a wide spectral range from the lower visible up to the near-infrared, often, symmetry effects are utilized to obtain particular optical responses.

Here, we observe strong chiroptical responses in the linear and nonlinear optical regime for chiral L-handed helicoid-III nanoparticles and quantify them by means of an asymmetric factor, the so-called g-factor. We calculate the linear optical g-factors for two distinct chiroptical resonances to −0.12 and –0.43 and the nonlinear optical g-factors to −1.45 and −1.63.

An important class of metasurface functionalities is associated with asymmetry in both the generation and transmission of light with respect to reversals of the positions of emitters and receivers. The nonlinear light–matter interaction in metasurfaces offers a promising pathway towards miniaturization of the asymmetric control of light. Here we demonstrate asymmetric parametric generation of light in nonlinear metasurfaces. We assemble dissimilar nonlinear dielectric resonators into translucent metasurfaces that produce images in the visible spectral range on being illuminated by infrared radiation. By design, the metasurfaces produce different and completely independent images for the reversed direction of illumination, that is, when the positions of the infrared emitter and the visible light receiver are exchanged. Nonlinearity-enabled asymmetric control of light by subwavelength resonators paves the way towards novel nanophotonic components via dense integration of large quantities of nonlinear resonators into compact metasurface designs."}],"user_id":"30525","author":[{"last_name":"Kruk","first_name":"Sergey S.","full_name":"Kruk, Sergey S."},{"last_name":"Wang","first_name":"Lei","full_name":"Wang, Lei"},{"first_name":"Basudeb","full_name":"Sain, Basudeb","last_name":"Sain"},{"last_name":"Dong","first_name":"Zhaogang","full_name":"Dong, Zhaogang"},{"last_name":"Yang","first_name":"Joel","full_name":"Yang, Joel"},{"full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101","first_name":"Thomas","id":"30525","last_name":"Zentgraf"},{"full_name":"Kivshar, Yuri","first_name":"Yuri","last_name":"Kivshar"}],"quality_controlled":"1","publisher":"Springer Science and Business Media LLC","keyword":["Atomic and Molecular Physics","and Optics","Electronic","Optical and Magnetic Materials"],"publication":"Nature Photonics","volume":16,"status":"public","date_created":"2022-06-21T05:52:43Z","intvolume":" 16","_id":"32088","main_file_link":[{"url":"https://arxiv.org/abs/2108.04425","open_access":"1"}],"year":"2022","citation":{"ieee":"S.

Our antennas contain a director and reflector deposited on a glass substrate, which are excited by a dipole emitter placed in the feed gap between the two elements. Full-wave simulations in conjunction with global optimization provide structures with an enhanced linear directivity as high as 119 radiating in the substrate. The high directivity is a result of the interplay between two dominant TE modes and the leaky modes present in the antenna director. Furthermore, these low-loss dielectric antennas exhibit a near-unity radiation efficiency at the operational wavelength of 780 nm and maintain a broad bandwidth. Our numerical results are in good agreement with experimental measurements from the optimized antennas fabricated using a two-step electron-beam lithography, revealing the highly directive nature of our structures.

In this work, we utilize two acoustic nonlocal metagratings that could support a direct conversion between an acoustic plane wave and a designated vortex mode to obtain the acoustic geometric phase, in which an orbital angular momentum conversion process plays a vital role. In addition, we realize the acoustic geometric phases of different orders by merely varying the orientation angle of the acoustic nonlocal metagratings. Intriguingly, according to our developed theory, we reveal that the reflective acoustic geometric phase, which is twice the transmissive one, can be readily realized by transferring the transmitted configuration to a reflected one. Both the theoretical study and experimental measurements verify the announced transmissive and reflective acoustic geometric phases.

However, the metasurfaces’ performance is tied to the unit cell’s efficiency and ultimately the surrounding environment it was designed for, thus reducing its applicability if exposed to altering refractive index media. Here, we report a method to increase a metasurface’s versatility by covering the high-index metasurface with a low index porous SiO2 film, protecting the metasurface from environmental changes while keeping the working efficiency unchanged. We show, that a covered metasurface retains its functionality even when exposed to fluidic environments.","lang":"eng"}],"user_id":"23547"}]
