In this framework, the self‐tunable metasurface consists of a liquid crystal spatial light modulator with a phase‐only modulated metasurface, combining a digital back end and an amplitude feedback neural network (AFNN) to achieve end‐to‐end online training. The loss gradient computed from the output prediction error is backpropagated through the digital network to the optical frontend, where it guides the adjustment of liquid crystal‐driven amplitude modulation in real time. SMPNN for object classification, achieving an accuracy of 99.2% for handwritten digits and 93.7% for fashion images, results that are largely comparable to those of traditional digital neural networks is used.

Nevertheless, the complex and time‐consuming manual manipulation of IMPFs remains a significant impediment to their widespread applications. Here, to the best of the knowledge, the first intelligent configuration of IMPF is experimentally demonstrated, featuring wideband center frequency tunability, flexible bandwidth reconfigurability, self‐stabilization, and excellent channel equalization simultaneously. The configuration is enabled by our proposed universal hybrid collaboration strategy, which fully unleashes the hardware potential of the optical device, thus enabling comprehensive synergy of multiple properties. Results show that the center frequency of IMPF is tuned from 2 to 48 GHz, covering microwave S band to Ka band, and the bandwidth is reconfigured from 0.66 to 4.15 GHz, with a rejection ratio of up to 37.67 dB. The roll‐off rate and shape factor reach as high as 17.50 dB GHz−1 and 0.78, respectively. Meanwhile, the maximum center frequency drift of IMPF over 3 h is reduced from 11.950 to 0.051 GHz even without a thermo‐electric cooler, indicating that the center frequency stability is enhanced by 234 times. The passband shape of the IMPF is dynamically adjusted to equalize frequency‐dependent fading, achieving up to 2.42 dB of intra‐channel fading compensation. This work highlights the potential of IMPFs based on intelligent configuration, unlocking new avenues for practical applications of microwave photonic signal processing.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"1 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314552","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}

In this study, the design and synthesis of a novel class of organic‐inorganic hybrid metal halides (OIHMHs), specifically (C6H16N2)2InCl7 (CIC) and its Sb3+‐doped derivatives are presented. These materials uniquely integrate anti‐Kasha emission, persistent luminescence, and self‐trapped excitons (STEs) emission. The CIC material exhibits blue and cyan emissions under varying UV excitations, accompanied by a 3‐s cyan persistent luminescence. Strategic doping of Sb3+ introduces yellow STEs emission, enabling color tuning from cyan to white and yellow. Advanced computational analyses, including density functional theory (DFT) and defect formation energy calculations, uncover the origins of these emissions. The anti‐Kasha behavior is attributed to π‐π* transitions of the organic cation, while the persistent luminescence arises from Cl vacancy (VCl) defects acting as energy storage traps. Leveraging these optical properties, a sophisticated binary coding system with six layers of anti‐counterfeiting security and CIC:5%Sb3+@SEBS composite film with outstanding spatial resolution have been developed. This work not only provides new research directions for prompt and delayed luminescence tuning in OIHMHs but also establishes a robust theoretical foundation for anti‐counterfeiting and information encryption fields.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"20 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314551","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}

The system employs a single‐mode telecommunication fiber for temporal dispersion and a programmable spatial light modulator to impose structured spatial patterns, with all signals detected by a single InGaAs photodetector. By correlating temporally stretched waveforms with spatial encodings, a 64 64 spatially resolved hyperspectral datacubes spanning 50 spectral bands over the 1550–1600 nm range are reconstructed. Furthermore, real‐time monitoring of dynamic liquid injection is demonstrated at a datacube refreshing rate of 12 Hz under sub‐Nyquist sampling.

The Maxwell fisheye lens with its inherent imaging properties is an excellent solution for multichannel intersections, however, its circular shape is not easily integrated with common planar input/output waveguides. Here, all‐silicon waveguide crossings are introduced based on Maxwell fisheye lenses reshaped via conformal transformation optics for improved planar waveguide integration in the terahertz range. Using effective medium techniques with subwavelength air inclusions, and crossings operating over the 220–330 GHz frequency band are designed and fabricated. The transformed lenses enable aberration‐free imaging without mode mismatch, implemented through a single deep reactive ion etching step. Experimental characterization reveals average insertion loss of 1.2 dB and crosstalk below –50 dB for the fundamental quasi‐transverse electric (TE) mode, with a 40% bandwidth across the entire 220–330 GHz band, while the quasi‐transverse magnetic (TM) mode is also supported for dual‐polarization applications.

Neural networks have been explored for phase retrieval and have shown some potential. However, they often require large datasets or lack generalization and precision.
