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}

Bragg scattering triggers the coherent four‐wave‐mixing process to generate new frequency components. Utilizing the perfect soliton crystal (PSC) linear‐wave scattering allows for the reconstruction of the comb spectrum, achieving spectral broadening and increasing the number of lines. By simultaneously separating two probe lasers on each edge of the PSC comb to stimulate the idler combs, the spectrum expands outward on both sides. Additionally, the study forms a pair of interleaved combs comprising PSC and idler combs with matching comb spacing to enhance the number of lines. The shape and efficiency of the idler comb are adjusted by varying the probe laser power and detuning. In comparison to the PSC comb with a 4% conversion efficiency, the idler comb exhibits a significantly higher conversion efficiency of nearly 50%. The findings demonstrate a straightforward method to reconstruct the PSC comb by introducing a probe laser to overcome the limitations imposed by microring properties.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"31 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143072505","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}

Nevertheless, designing mode converters for hybrid multiplexing remains challenging. Reconfigurable and scalable multichannel parallel mode converters offer an attractive solution for efficient mode switching with a small footprint. In this paper, a compact and high‐performance dual‐polarization multichannel parallel mode order converter based on metamaterials is proposed, which consists of two components. One of the components is the flexible and compact multimode beam splitter designed by the rapidly convergent variable step size binary search algorithm. The other component is the dual‐polarization phase shifter that maximizes the feature size of the non‐subwavelength structure, significantly reducing the adverse effects of over‐etching. The experimental results demonstrate that the insertion loss of each mode is below 1.96 dB, while the crosstalk of each input mode is lower than −13.4 dB. The feasibility of high‐speed transmission is demonstrated by transmitting 30 GBuad 16‐quadrature amplitude modulation (QAM) signals on the device. This device is believed to be the first dual‐polarization multichannel parallel mode converter reported to date. This innovative device holds great potential for enhancing communication capacity in reconfigurable and scalable hybrid multiplexed transmission systems.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"14 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143072507","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}
