Typically, bulky pulse compressors consisting of gratings or prisms are used\r\nto address this issue by precompensating the dispersion of the optical components. 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"}],"issue":"8","publication":"Nano Letters","keyword":["Mechanical Engineering","Condensed Matter Physics","General Materials Science","General Chemistry","Bioengineering"],"type":"journal_article","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"file":[{"creator":"zentgraf","date_created":"2023-04-18T05:50:19Z","access_level":"closed","file_size":1315966,"file_name":"acs.nanolett.2c04980.pdf","date_updated":"2023-04-18T05:50:19Z","relation":"main_file","content_type":"application/pdf","success":1,"file_id":"44045"}],"date_created":"2023-04-18T05:47:22Z","has_accepted_license":"1","status":"public","ddc":["530"],"user_id":"30525","volume":23,"page":"3196 - 3201","_id":"44044","funded_apc":"1","publisher":"American Chemical Society (ACS)","quality_controlled":"1","project":[{"_id":"53","name":"TRR 142: TRR 142"},{"name":"TRR 142 - B: TRR 142 - Project Area B","_id":"55"},{"name":"TRR 142 - B09: TRR 142 - Subproject B09","_id":"170"},{"name":"TRR 142 - C07: TRR 142 - Subproject C07","_id":"171"},{"name":"TRR 142 - C: TRR 142 - Project Area C","_id":"56"}],"file_date_updated":"2023-04-18T05:50:19Z","citation":{"mla":"Geromel, René, et al. “Compact Metasurface-Based Optical Pulse-Shaping Device.” <i>Nano Letters</i>, vol. 23, no. 8, American Chemical Society (ACS), 2023, pp. 3196–201, doi:<a href=\"https://doi.org/10.1021/acs.nanolett.2c04980\">10.1021/acs.nanolett.2c04980</a>.","bibtex":"@article{Geromel_Georgi_Protte_Lei_Bartley_Huang_Zentgraf_2023, title={Compact Metasurface-Based Optical Pulse-Shaping Device}, volume={23}, DOI={<a href=\"https://doi.org/10.1021/acs.nanolett.2c04980\">10.1021/acs.nanolett.2c04980</a>}, number={8}, journal={Nano Letters}, publisher={American Chemical Society (ACS)}, author={Geromel, René and Georgi, Philip and Protte, Maximilian and Lei, Shiwei and Bartley, Tim and Huang, Lingling and Zentgraf, Thomas}, year={2023}, pages={3196–3201} }","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.","lang":"eng"}],"issue":"1","publication":"Nature Communications","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"type":"journal_article","keyword":["General Physics and Astronomy","General Biochemistry","Genetics and Molecular Biology","General Chemistry","Multidisciplinary"],"date_created":"2023-07-06T06:34:37Z","file":[{"date_created":"2023-07-06T06:40:28Z","creator":"zentgraf","file_id":"45869","success":1,"content_type":"application/pdf","file_name":"NatureCommun_Ahmed_2023.pdf","file_size":4341041,"access_level":"closed","relation":"main_file","date_updated":"2023-07-06T06:40:28Z"}],"has_accepted_license":"1","status":"public","volume":14,"user_id":"30525","ddc":["530"],"_id":"45868","publisher":"Springer Science and Business Media LLC","quality_controlled":"1","citation":{"ama":"Ahmed H, Ansari MA, Li Y, Zentgraf T, Mehmood MQ, Chen X.

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"}]},{"user_id":"30525","volume":9,"page":"784–792","_id":"30195","publisher":"American Chemical Society (ACS)","status":"public","oa":"1","external_id":{"arxiv":["arXiv:2202.13594"]},"quality_controlled":"1","citation":{"mla":"Spreyer, Florian, et al. “Second Harmonic Optical Circular Dichroism of Plasmonic Chiral Helicoid-III Nanoparticles.” <i>ACS Photonics</i>, vol. 9, no. 3, American Chemical Society (ACS), 2022, pp. 784–792, doi:<a href=\"https://doi.org/10.1021/acsphotonics.1c00882\">10.1021/acsphotonics.1c00882</a>.","bibtex":"@article{Spreyer_Mun_Kim_Kim_Nam_Rho_Zentgraf_2022, title={Second Harmonic Optical Circular Dichroism of Plasmonic Chiral Helicoid-III Nanoparticles}, volume={9}, DOI={<a href=\"https://doi.org/10.1021/acsphotonics.1c00882\">10.1021/acsphotonics.1c00882</a>}, number={3}, journal={ACS Photonics}, publisher={American Chemical Society (ACS)}, author={Spreyer, Florian and Mun, Jungho and Kim, Hyeohn and Kim, Ryeong Myeong and Nam, Ki Tae and Rho, Junsuk and Zentgraf, Thomas}, year={2022}, pages={784–792} }","ama":"Spreyer F, Mun J, Kim H, et al.

By breaking certain spatial symmetries, chiral structures arise and provide robust chiroptical responses to these plasmonic resonances. 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. The results demonstrate that the chirality of the helicoid-III nanoparticles is strongly enhanced in the nonlinear regime."}],"related_material":{"link":[{"relation":"research_paper","url":"https://pubs.acs.org/doi/full/10.1021/acsphotonics.1c00882"}]},"publication":"ACS Photonics","issue":"3"},{"citation":{"ieee":"B.

However, pushing the concept of the geometric phase toward the acoustic community still faces challenges. 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. Moreover, the reconfigurability and continuous phase modulation that covers the 2π range shown by the acoustic geometric phases provide us with the alternatives in advanced acoustic wavefront control.","lang":"eng"}]},{"oa":"1","citation":{"ama":"Geromel R, Weinberger C, Brormann K, Tiemann M, Zentgraf T.

However, the current method to generate and manipulate GPVBs requires a complex and bulky optical system, hindering further investigation and limiting its practical applications. Here, a compact metasurface approach for generating and manipulating GPVBs in multiple channels is proposed and demonstrated, which eliminates the need for such a complex optical setup. A single metasurface is utilized to realize various superpositions of GPVBs with different combinations of topological charges in four channels, leading to asymmetric singularity distributions. The positions of singularities in the superimposed beam can be further modulated by introducing an initial phase difference in the metasurface design. The work demonstrates a compact metasurface platform that performs a sophisticated optical task that is very challenging with conventional optics, opening opportunities for the investigation and applications of GPVBs in a wide range of emerging application areas, such as singular optics and quantum science."}],"article_number":"2203044","language":[{"iso":"eng"}],"doi":"10.1002/adma.202203044","title":"Multichannel Superposition of Grafted Perfect Vortex Beams","year":"2022","publication_identifier":{"issn":["0935-9648","1521-4095"]},"author":[{"full_name":"Ahmed, Hammad","first_name":"Hammad","last_name":"Ahmed"},{"first_name":"Yuttana","last_name":"Intaravanne","full_name":"Intaravanne, Yuttana"},{"full_name":"Ming, Yang","last_name":"Ming","first_name":"Yang"},{"full_name":"Ansari, Muhammad Afnan","first_name":"Muhammad Afnan","last_name":"Ansari"},{"full_name":"Buller, Gerald S.","last_name":"Buller","first_name":"Gerald S."},{"orcid":"0000-0002-8662-1101","last_name":"Zentgraf","first_name":"Thomas","full_name":"Zentgraf, Thomas","id":"30525"},{"full_name":"Chen, Xianzhong","first_name":"Xianzhong","last_name":"Chen"}],"date_updated":"2023-05-12T11:20:44Z","publication_status":"published","intvolume":"        34","article_type":"original","citation":{"short":"H.

In addition, such hybrid metasurfaces show SHG in polarization states, where SHG is usually forbidden for either 1L-WS2 or plasmonic nanoantennas. By comparing the SHG in these channels with the SHG generated by the hybrid metasurface components, we detect an enhancement of the SHG signal by a factor of more than 40. Meanwhile, an attenuation of the SHG signal in usually allowed polarization states is observed. Our study provides valuable insight into hybrid systems where symmetries strongly affect the SHG and enable tailored SHG in 1L-WS2 for future applications."}],"date_created":"2021-10-07T07:39:27Z","type":"journal_article","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"}],"status":"public","page":"16719-16728","_id":"25605","funded_apc":"1","user_id":"30525","volume":15,"citation":{"short":"F.

In our concept, metasurface holograms are used as spatially separable shares that carry encrypted messages in the form of holographic images. Two of these shares can be recombined by bringing them close together. Light passing through this stack of metasurfaces accumulates the phase shift of both holograms and optically reconstructs the secret with high fidelity.

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.

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.
