Diffractive Optical Neural Networks (DONNs) have recently been demonstrated to efficiently recover images with scattering distortions using coherent light in terahertz spectrum [eLight, 2022, 2(1):4]. However, the study [Optica, 2024, 11(12):1742] has demonstrated that DONN designed for coherent light may not function optimally with low coherent sources. Consequently, the performance of DONNs in image‐based reconstruction tasks under visible and incoherent light requires further investigation. For this purpose, a three‐layer DONN is constructed to reconstruct images occluded by unknown random diffusers under coherent/incoherent visible light. The results show that the Pearson correlation coefficient (PCC) of the coherent DONNs reconstructed images can reach 0.863–0.971 for diffuser correlation lengths of (: a single neuron size of 8 µm); when of , the PCC of the incoherent diffractive optical neural networks (IC‐DONNs) reconstructed images can reach 0.861–0.899. It is found that the dynamic phase modulation mechanism introduced by randomly generated diffusers during network training enhances the adaptation of coherent DONN to spatial coherence variations of the light source. It is believed that these findings will advance the application of DONN for imaging under natural environmental conditions.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"100 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140895","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}

Conventional implementations typically necessitate complex optical assemblies, temporal multiplexing strategies, and specialized active illumination sources, imposing fundamental limitations on system miniaturization and practicality. Drawing inspiration from human visual perception, particularly disparity images and optical structures, a metasurface capable of 4D imaging is demonstrated through single‐shot acquisition. Leveraging polarization multiplexing principles and the non‐diffracting, self‐accelerating properties of Airy beams, the metasurface produces spin‐decoupled point spread functions (PSFs) exhibiting horizontal displacement correlated with object depth. This configuration enables the generation of disparity‐equivalent images in the left‐ and right‐handed circular polarization channels. By combining these with the proposed image restoration and depth retrieval algorithms, 4D imaging encompassing 3D imaging and polarization analysis is achieved. This compact multidimensional imaging platform demonstrates significant potential to advance machine vision and autonomous driving applications while offering foundational insights for further high‐performance imaging system development.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"41 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140898","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}

While NLO crystals offer unmatched bandwidth and efficiency, their miniaturization contradicts the phase‐matching and crystal size requirements. Here, a non‐centrosymmetric metal–organic framework (MOF) crystal is reported that enables broadband, multi‐wavelength coherent light generation on a microscale. By overcoming the limitations of the most conventional NLO crystals, MOF microcrystal of a fixed orientation supports simultaneously a wide range of NLO effects, initiated by two pump wavelengths in a free space. The second‐ and the third‐order optical nonlinearities in arbitrary direction, coupled with a 1.5 nm3 unit cell and the huge hyperpolarizability of this MOF, facilitates simultaneously a set of the sum‐frequency generation and cascaded processes that span over 350 nm with 7 to 32 coherent peaks of uniform intensity and a quality factor up to 180.

Extending BHD at mid‐infrared wavelengths (4–11 µm), given the reduced scattering and favourable transparent atmospheric windows, could enable robust earth‐satellite links and few‐photon imaging in high‐noise environments. Currently, quantum applications at these wavelengths are hindered by the lack of high‐sensitivity, room‐temperature photoreceivers; moreover, mid‐infrared single‐photon‐detectors reported to date (superconductors, single‐electron‐transistors, or avalanche‐photodiodes) require cryogenic operation, limiting practicality. Here, a room‐temperature BHD system operating at 4.6 µm‐wavelength with atto‐watt sensitivity level, corresponding to a few tens of photons per second, is demonstrated. This result is obtained by selecting commercially available photodetectors with the highest detectivity and exploiting two heterodyne setups ‐one involving a single quantum‐cascade‐laser (QCL) and an acousto‐optic‐modulator (AOM), and the other one including two QCLs with mutual coherence ensured by a phase‐locked‐loop. Combining a sufficiently high local oscillator (LO) power and the high phase‐coherence between signal and LO is crucial to push the system noise‐equivalent‐power (NEP) to values approaching the shot‐noise‐limit, as confirmed by few‐photons interferometry measurements. This work not only validates viable methods to detect ultra‐low‐intensity signals, but is also potentially scalable to the entire wavelength range already accessible by state‐of‐the‐art mid‐infrared technology.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"10 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145133770","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}

Additionally, by leveraging the information mapping into a multitude of orbital‐angular‐momentum (OAM) modes, one can expect a substantial capacity boost in the optical signal transmission through complex environments. However, most of the currently known techniques of this kind are conceptually restricted to the static scattering mechanism. Here, the possibility of transmitting information in a dynamic scattering scenario is investigsted via the intensity cross‐correlation of pairs of the OAM‐dependent speckles. It is theoretically predicted and experimentally confirmed that the intensity cross‐correlation between synchronized OAM‐dependent speckles with distinct OAM indices is immune to the dynamic scattering process, a finding that can be used as a robust mitigation tool against random media. The pair‐OAM mode sorting is then demonstrated under the dynamic scattering regime without any prior knowledge of the scattering process. The results can significantly expand the application scope of the OAM‐mediated information transfer in the presence of complex environments that still constitutes a persistent challenge for traditional optical technologies.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"27 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140901","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}

If electrically pumped lasing could be demonstrated using these materials, many new classes of optical sensors and detectors could be realized leaving a profound impact on society. Devices fabricated from conducting molecules and polymers have already been demonstrated with polaron densities higher than those which theoretically lead to lasing action; however, threshold remains elusive. Herein, a polymer micro‐OLED is reported that achieves record room‐temperature current densities of 1.5 , however despite this, it is not high enough to reach lasing threshold. Using a combination of nanosecond spectrographic techniques and detailed simulation, the mechanisms inhibiting lasing action is unraveled. It is shown that although as previously thought singlet‐triplet annihilation is important in pushing threshold higher, photon absorption by excited triplets is as (if not more) important in inhibiting lasing action. The complex dynamics of singlets, triplets, and free/excited polarons in these disordered materials are visualized; establishing a pathway to overcome these bottlenecks and realise electrically pumped organic lasing action.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"31 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140902","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 particular, varifocal achromatic metalenses are urgently needed for biochemical discrimination imaging and nondestructive inspection. Here, a design is proposed to realize a varifocal achromatic metalens. It works on the simultaneous compensation of the diffraction dispersion of a foci‐switchable basic phase profile on the basis of a properly preset group delay of a propagation phase. The concept is demonstrated with a liquid crystal integrated silicon metalens. The major axis orientation of cylindroid meta‐atoms supplies a fixed geometric phase, the photopatterned liquid crystal provides a switchable geometric phase, and the compensation originates from the shape variation of cylindroid meta‐atoms. Both simulations and experiments verify the switchable achromatic focusing at two distinct foci (10.20 and 13.76 mm) across 1.0–1.6 THz. Dual‐depth multispectral imaging is further demonstrated with two medicaments, exhibiting its potential for nondestructive safety screening and pharmaceutical identification.
