However, integrating precise control in information security technologies with highly sensitive temperature sensing remains a significant challenge. Here, a multilayer core–shell upconversion nanoparticle (UCNP) system is presented that enables dynamic dual‐color emission switching and highly sensitive temperature sensing through controlled energy transfer mechanisms. By tuning the excitation wavelength, power density, and pulse width, the system exhibits a green‐to‐blue emission transition with multimodal tunability. Using fluorescence intensity ratio techniques, maximum relative sensitivity of 1.85% K−1, demonstrating superior temperature detection performance is achieved. Furthermore, the tunable multicolor emission properties of UCNPs enable diverse applications in information security, including dynamic pattern recognition, Morse code encryption, and quick response code‐based anti‐counterfeiting. This research not only broadens the application scope of UCNPs in security and environmental monitoring but also offers perspectives on the design of multifunctional optical materials.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"4 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143789693","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, the frame rate of conventional MIR imagers is typically limited by readout electronics and detection sensitivity, especially for large spatial formats with massive pixels. Here, a high-speed MIR upconversion imaging system based on time-multiplexed nonlinear structured pumping is devised and implemented. Specifically, the dynamic infrared scene is optically gated by a sequence of spatially periodical pump patterns in a nonlinear crystal, which facilitates both rapid temporal encryption and sensitive upconversion detection. Then, the upconverted frames are superimposed onto a silicon camera within a single exposure, thus resulting in a multiplexed snapshot in the spatial-frequency domain. Finally, the sub-exposure images, corresponding to distinct transient events, can be computationally deciphered and reconstructed by the frequency recognition algorithm based on band-pass filtering and Fourier transform operations. The achieved frame rate is tenfold boosted to 10 000 frames per second without compromising the megapixel spatial format, which allows continuous real-time MIR videography at high speed and high definition. The presented approach can be readily extended to far-infrared or terahertz spectral regions, with an aim of performing high-throughput and high-sensitivity observation of transient phenomena with high temporal complexity.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"59 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143798311","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}

Their scale is often linked to that of the operands, therefore lack flexibility when dealing with variable data sizes. A novel multi‐dimensional minimalist photonic processor (MD‐MPP) architecture is demonstrated, capable of simultaneously and scalably utilizing time, wavelength, and space multiplexing to achieve high throughput, versatile operations, and flexible data adaption, performing all‐optical multiply‐and‐accumulate (MAC) operations for vector dot‐products, matrix‐vector‐multiplication, single‐/multi‐kernel convolution in time‐recursive, wavelength‐parallel and spatial‐parallel fashions.

However, mainstream two-stage EP-based chiral mode transfer has encountered critical bottlenecks, as current research primarily focuses on operating within a single dimension (polarization or mode). Here, high-dimensional chiral transfer by bi-directionally encircling EPs is presented, which implements distinct chiral transfers for different polarizations. Consequently, the high-dimensional chiral transfer yields unconventional output mode states that are influenced not only by the injection direction but also by the polarization state. Meanwhile, leveraging the birefringence effect of the silicon waveguide, high-performance high-dimensional chiral transfer is experimentally demonstrated using the bi-directionally encircling-EP approach, which demonstrates robustness against encircling loop selection. Moreover, the occurrence of chiral transfer can also be controlled by polarization. The findings not only pave the way for further exploration of high-dimensional non-Hermitian systems but also unlock opportunities for a wide variety of high-capacity applications.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"37 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143775867","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, in the field of optical fiber processing, due to the position-dependent aberration induced by optical fiber's cylindrical geometry and protective coating, achieving precise control over the intensity uniformity and positioning accuracy of multi-foci presents significant challenges, which complicates the realization of high-quality parallel inscription. Here, an adaptive and high-throughput parallel inscription strategy for multi-core fiber (MCF) is presented. The depth-dependent aberration phase for each focus is derived, facilitating the generation of astigmatism-corrected holograms using the Gerchberg-Saxton-weighted algorithm. Meanwhile, an online image processing algorithm is employed to measure the internal core distribution of MCF, enabling the adaptive update of holograms. As a demonstration, parallel fiber Bragg grating (FBG) array inscription in seven-core fiber is achieved. Experimental results show that the average intra-node reflectivity difference can be controlled within 2 dB. Moreover, 7 FBGs can be inscribed simultaneously within 6 s, improving the inscription efficiency by an order of magnitude. The proposed method is fast, versatile, and robust, thus providing a promising solution for the efficient fabrication of advanced photonic devices inside optical fiber.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"15 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758112","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}

A new design and ultrafast laser fabrication method of an all‐glass nanohole metasurface is proposed. High‐aspect‐ratio nanoholes with subwavelength periods, tunable depths, and fixed duty cycle function as phase shift units, realizing idealized linear 2π phase delay to support great light modulation performance. A non‐diffracting laser lithography approach is developed to fabricate nanohole arrays, using a unique Bessel beam modulated by a reversed‐axicon phase diagram to guarantee hole diameter consistency along the depth. Combining with thermal annealing and chemical etching, surface and subsurface damage‐free nanohole arrays are produced with periods down to 800 and precisely controlled depths over 10 µm. The capability helps realize the rapid fabrication of a high‐performance all‐glass nanohole metalens with ≈97% modulation efficiency at 1.55 µm. A large 2 cm‐diameter metalens and diverse optical devices like axicon, vortex wave plate, and blazed grating are also demonstrated.
