Here, it is demonstrated that freestanding oxide membranes supply a reconfigurable platform for nano-photonics based on propagating surface phonon polaritons. Infrared near-field imaging and spectroscopy enabled by a tunable ultrafast laser are applied to study pristine nano-thick SrTiO3 membranes prepared by hybrid molecular beam epitaxy. As predicted by coupled mode theory, it is found that strong coupling of interfacial polaritons realizes symmetric and antisymmetric hybridized modes with simultaneously tunable negative and positive group velocities. By resolving reflection of these propagating modes from membrane edges, defects, and substrate structures, their dispersion is quantified with position-resolved nano-spectroscopy. Remarkably, polariton negative dispersion is found to be both robust and tunable through choice of membrane dielectric environment and thickness, and proposes a novel design for in-plane Veselago lensing harnessing this control. This work lays the foundation for tunable transformation optics at the nanoscale using polaritons in a wide range of freestanding complex oxide membranes.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202501452","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, focus is placed on hypervalent gallium azobenzene complexes with variable coordination motifs because of a wide accessible space around gallium. The six-, five-, and four-coordinated gallium azobenzene complexes are isolated with pyridine ligands, and it is observed that the coordination of pyridine can dynamically change in the solution. Interestingly, the enhancement of the absolute fluorescence quantum yields is observed by the suppressing structural relaxation as increasing the coordination number. Furthermore, it is found that the emission efficiency is enhanced as increasing donor number which represents the strength of Lewis basicity. Finally, it is demonstrated that the filter paper soaked by the synthesized gallium complex is prepared, and it worked as a turn-on luminescent sensor to easily visualize strength of Lewis basicity of solvents by simply dropping the solvent on the paper. The findings are valuable for the development of designable and controllable stimuli-responsive materials focusing on the inherent properties of the main-group elements and π-conjugated systems.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 28","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a flexible and transparent beam-steering metasurface is demonstrated, based on a three-layer fine metal line (FML) network patterned on PET substrates with an interleaved air gap. The metasurface enables linear polarization rotation and broadband phase compensation while achieving high optical transparency (∼70%) and mechanical flexibility. The transmitarray is optimized to steer beams over a broad frequency range from 13 to 32 GHz through passive frequency-dependent phase dispersion. Simulations and measurements confirm consistent beam deflection from 26° to 9°, with a peak gain of 26.03 dBi and stable aperture efficiency above 40%. Conformal simulations demonstrate that beam-steering performance is maintained under bending angles up to 20°, with no degradation in optical or electromagnetic functionality. Combining with ultra-wideband operation, transparency, conformability, and scalable fabrication, the proposed metasurface presents a promising solution for next-generation transparent antennas, radomes, and smart wireless–photonic platforms.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 29","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, the first realization of on-chip electron emission control using an active THz metasurface is reported. The device integrates resonant dipole antennas and bias arms on a fused silica substrate, enabling precise modulation of electron trajectories through electrostatic control. Experimental results, supported by particle-in-cell simulations, reveal that electron emission via Fowler–Nordheim tunneling can be dynamically steered by varying the applied bias. A positive bias suppresses emission by attracting electrons to the bias arms, while a negative bias repels them, allowing trajectory control and the emergence of new emission features. Time-of-flight measurements show distinct shifts in electron emission behavior, with strong correlation to bias voltage and THz field strength. This work demonstrates a practical approach to integrating ultrafast electron control into chip-scale systems.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 28","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202500104","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a single layer of graphene nanoribbons as a templating layer, an aligned layer of aggregated molecules is obtained. The molecular layer displays anisotropic optical properties resembling those of a biaxial crystal. The anisotropic excitonic component in the cavity results in strongly polarization-dependent light-matter interaction and in increased Rabi-energies. The increased light-matter interaction is possibly due to reduced molecular disorder in the templated molecular layer. This conclusion is supported by an analysis based on a multi-oscillator model. Photoluminescence microspectroscopy is further used to demonstrate that the light-matter coupling is spatially homogeneous. This study introduces molecular templating to strong light-matter studies. The reduced disorder of the system as a consequence of templating is highly beneficial for engineering light-matter interaction.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"13 28","pages":""},"PeriodicalIF":7.2,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202500998","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
