However, traditional methods like chemical vapor deposition and molecular beam epitaxy require highly controlled environments and specialized equipment, limiting scalability and precision. To address these challenges, a single-laser platform is presented for selective tweezing and immobilization of colloids (STIC) that integrates particle manipulation, assembly, and stabilization in one system. STIC utilizes a femtosecond laser at ultra-low power for precise, contact-free optical manipulation of colloids without material damage. At higher power, the same laser enables two-photon polymerization (TPP) to immobilize colloids securely in their intended positions. Using STIC, the assembly of 3D structures from dielectric beads to patterned arrangements of transition metal dichalcogenides (TMDs e.g., MoS2) is demonstrated. Also a TPP-fabricated handle as an intermediate support is incorporated which significantly enhances the optical tweezing efficiency of TMDs. The single-laser design eliminates the need for dual-laser systems, simplifying optical alignment, reducing heat damage, and improving efficiency. Additionally, it is shown that STIC supports direct multiphoton imaging for in situ inspection during fabrication. This work establishes a versatile, scalable optical platform for high-precision microstructure fabrication, offering a pathway to overcome current limitations in micro- and nanomanufacturing.","PeriodicalId":7263,"journal":{"name":"Advanced Photonics Research","volume":"6 5","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adpr.202500003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The metamaterial consists of a periodically perforated gold membrane that exhibits the extraordinary optical transmission (EOT) effect, combined with a parallel silicon membrane separated by an air gap. This structure acts as a band-pass filter, with its spectral position highly sensitive to the separation gap between the membranes, which influences the resonance conditions for EOT. Numerical simulations predict tunability across the entire LWIR range with a membrane displacement of just 0.5 μm. This concept is experimentally demonstrated through vertical electrostatic actuation of the silicon membrane relative to the gold layer facilitated by a micro-electromechanical systems (MEMS) approach. The measured optical transmission of the fabricated MEMS-enabled, spectrally tunable plasmonic metamaterial shows good agreement with the numerically modeled spectral filter characteristics. Further refinement of this method could pave the way for a variety of low-cost, low-power miniature devices, enhancing spectroscopy and multispectral imaging capabilities in the thermal infrared range.","PeriodicalId":7263,"journal":{"name":"Advanced Photonics Research","volume":"6 5","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adpr.202400185","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photonic quantum sources based on atomic ensembles are excellent candidates due to their brightness, low noise, and narrowband characteristics. Herein, a new platform for a highly efficient biphoton source is presented using a thin, dense atomic medium from a hot 1 mm-long chip-scale Cs atomic vapor cell. Strongly correlated bright biphotons are generated via spontaneous four-wave mixing from a dense atomic ensemble based on the 6S1/2–6P3/2–6D5/2 transition of 133Cs. Biphoton source achieves a detected biphoton count rate of 100 kilo-counts per second, a heralding efficiency of 15%, and a maximum normalized crosscorrelation function value of 100 between the signal and idler photons, despite the low detector efficiency of a silicon avalanche photodetector being less than 25% at 917 nm. Herein, the maximal violation of the Cauchy–Schwarz inequality by a factor greater than 106 at a pump power of 1 μW is obtained.

In this direction, the use of additional layers in the well-established silicon-based modules represents a challenging strategy. In this context, the present work is devoted to the optimization of a downshifting (DS) system made of the NaGdF4 matrix in the form of thin film as a host material for the europium-luminescent ions. The Eu-doped NaGdF4 system is fabricated through a sol–gel approach starting from a mixture of Na(hfa)•tetraglyme, Gd(hfa)3•diglyme, and Eu(hfa)3•diglyme in ethanol solution. The operative parameters are finely tuned to pursue the formation of compact and polycrystalline films. Particularly, the annealing treatment, the nature of the substrate, and the doping ion percentage are the key parameters for the reproducible and selective formation of NaGdF4 in the form of the beta (hexagonal) crystal structure with promising luminescent properties. Morphological, structural, and compositional features are deeply studied through field-emission scanning electron microscopy, X-ray diffraction analysis, and energy-dispersive X-ray analysis, respectively. The luminescence investigations confirm the properties of the Eu-doped NaGdF4 as DS system.","PeriodicalId":7263,"journal":{"name":"Advanced Photonics Research","volume":"6 5","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adpr.202400153","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, an integrated approach that combines a theoretical investigation of the optical properties of Ni–Al compounds with an optimized geometrical microdevice design is reported. Benchmarking of the optical properties and device performance revealed that NiAl exhibited the best optical properties among the surveyed families of Ni–Al intermetallic compounds, comparable to those of conventional plasmonic materials in the IR region. Additionally, the NiAl-based microdevices exhibited an excellent quality of 692, making them promising high-temperature plasmonic superalloys for IR thermophotonic applications. In addition, the experimental dielectric function in the IR region was consistent with the simulated value. Simultaneously, various designs of plasmonic metamaterial structures are modeled successfully based on NiAl, demonstrating the good performance of this material as a perfect spectroscopic absorber and emitter operating in the IR region.","PeriodicalId":7263,"journal":{"name":"Advanced Photonics Research","volume":"6 4","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adpr.202400093","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
