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. The scheme for a highly efficient photon source is believed to be useful for scalable quantum networks.","PeriodicalId":7263,"journal":{"name":"Advanced Photonics Research","volume":"6 4","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adpr.202400214","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762336","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}

However, no reports of their thermophotonic applications, such as high-temperature IR emitters, have been reported. 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}

However, fabricating traditional array-based imaging detectors with these materials remains challenging. Cadmium sulfide (CdS), a historically significant semiconductor material, has been extensively used in optoelectronic devices due to its remarkable photoelectric properties and chemical stability. Notably, a unique type-I heterojunction can be formed by combining 2D CdS, prepared through chemical vapor deposition, with the first-generation semiconductor germanium (Ge). His heterojunction photodetector exhibits outstanding photoelectric performance, achieving a responsivity of 54 mA W−1 and a detectivity of 1.4 × 109 Jones under zero bias, with a spectral response range spanning from 265 to 1550 nm. Herein, the CdS/Ge heterojunction photodetector with the emerging single-pixel Hadamard algorithm, addressing challenges in nonvisible imaging that conventional imaging systems traditionally encounter, is integrated. This approach facilitates low-sampling-rate image reconstruction across a broad spectral range and under scattering conditions. It is anticipated that this work will significantly contribute to future advancements in broadband imaging applications.","PeriodicalId":7263,"journal":{"name":"Advanced Photonics Research","volume":"6 3","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adpr.202400190","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530618","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}

However, current multimodal imaging systems typically use multiple or specially designed excitation lasers. Furthermore, previous studies have reported only three or four types of imaging modalities, limiting the number of imaging targets. This study develops an imaging system based on a single commercialized 1550 nm fiber laser and integrates five imaging modalities: second harmonic generation, third harmonic generation, two-photon fluorescence, three-photon fluorescence, and reflected confocal microscopy. Utilizing the characteristics of different imaging modalities, various biological components in biological tissues can be revealed simultaneously and cell movement in a complex biological environment can be traced noninvasively. The capacity of deep imaging has also been demonstrated in the mouse brain. The results show that the proposed multimodal microscopy system has great application potential in biomedical fields, such as tumor diagnosis and immunotherapy.","PeriodicalId":7263,"journal":{"name":"Advanced Photonics Research","volume":"6 3","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adpr.202400115","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530597","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}
