The sensitivity and resolution of conventionally used QPM are fundamentally limited by environmental noise. Recently, quantum phase microscopy has been proposed. The research on it has made some progress and has shown many advantages over the classical one, such as greater robustness and higher contrast. However, the phase resolution of existing quantum phase microscopies remains very low, often confined to the qualitative measurement level. Here, to resolve these practical limitations, we introduced polarization entanglement-enabled quantum holographic technology into the microscopy system and constructed a new type of quantum phase microscopy, namely quantum holographic microscopy. By improving the existing quantum holographic scheme, our microscope system can be used to measure both various non-biological phase samples and label-free biological samples. The experimental results show that the phase resolution is improved by an order of magnitude compared with that of existing quantum phase microscopes. Moreover, the system has good robustness and can still obtain clear images in the presence of strong classical noise. The newly constructed quantum microscopic system is expected to have broad applications in industrial production, medicine, biological research, and other fields.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"1 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143258685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These devices' properties are susceptible to material composition and structural design. Nanofabrication techniques, such as optical lithography, e-beam lithography, two-photon polymerization, and direct laser writing, have been widely applied to fabricate nanophotonic devices. Notably, rewritable fabrication stands out due to its low cost, flexibility, efficiency, and multi-functionality. In this paper, a novel rewritable nanofabrication technique is proposed, which combines electrochemical reactions with direct laser writing, to fabricate nanophotonic devices on low-cost indium tin oxide (ITO) films. The experimental results have demonstrated that high-quality and erasable photonic structures such as diffraction gratings and holography masks can be directly fabricated using our technique. Hence, it is believed that this method can be applied in diverse fields such as nanophotonics, optoelectronic devices, biosensors, micro-electromechanical systems, and nonlinear optics.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"19 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143083904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, sensing in the terahertz band presents notable challenges. Here, a dual-port coupled SLSPs resonator and a single-port coupled SLSPs resonator are proposed with phase separated excitation, both exhibiting high-Q-factors in the terahertz band. The dual-port coupled SLSPs can sustain both odd resonance mode and even resonance mode, whereas the single-port coupled SLSPs can generate vortex wave resonance modes and asymmetric modes. In the measurement, the highest Q value of the dual-port resonator is 69 at the frequency of 179.4 GHz. Equally noteworthy is the single-port resonator, which reaches a groundbreaking Q-factor of 405.4 at the frequency of 150 GHz, marking a significant advancement in the Q-factors of passive devices. Biosensing for Bletilla, Fritillaria, Rhubarb, and glucose in the terahertz band is implemented, with the maximum frequency shift of 15.8 GHz for the dual-port coupled SLSPs and 7.8 GHz for the single-port coupled SLSPs. The maximum sensing figures of merits (FoM) are 4.1 and 12.9RIU−1 for the dual- and single-port resonators, respectively, underscoring substantial potentials of this work in the realm of terahertz sensing.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"29 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143124713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current methods often convert tensor convolutions into matrix multiplications, leading to data replication, additional memory usage and increased hardware complexity. Here, a high-bit-efficiency optical tensor convolution accelerator with reduced data redundancy and lower memory consumption is presented. The bit-efficiency of the optical tensor convolution accelerator is first explored, significantly improving its effective computing power by utilizing the spatial dimension. Consequently, the optical tensor convolutional accelerator operates at speeds exceeding 3 Tera Operations Per Second (TOPS)—the fastest single-kernel optical convolutional accelerator to date, to the best of authors' knowledge. Its performance is validated on handwritten digit recognition and histopathologic cancer detection tasks, achieving 93.8% and 77% accuracy, respectively, closely matching in-silico results. This approach simultaneously multiplexes the physical dimensions—wavelength, time, and space—and leverages the parallelism and high throughput of light, enabling efficient optical processing of tensor data with significant computational power.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"45 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143083906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with mechanoluminescent (ML) materials, the research on physical mechanism and sensing application of MQ materials is still insufficient. Moreover, existing mechano-optical materials typically respond only to dynamic stress, while ML materials are unable to exhibit luminescence under static stress, restricting their utility in stress-sensing applications. In this work, the MQ characteristics of CaZnOS:Cu+ are systematically studied, which displays a linear mechano-optical response to dynamic and static stress. Furthermore, this material shows a sensitive response to micro-strain in stretching tests. Therefore, a novel mechanical switch device is introduced combined with CaZnOS:Cu+ and a ML material LiTaO3:Tb3+. By comparing the alteration in luminescence intensity during stretching, different stages of stress are digitally encoded, achieving both dynamic and static stress sensing and effectively differentiating the information output. These findings provide a new approach for multi-mode dynamic and static stress sensing by utilizing mechano-optical materials and pave a significant avenue for the information integration of mechano-optical materials in the field of stress sensing.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"6 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143077177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
