The challenges of nonlinear conversion of waveguide modes are to simultaneously fulfill the phase-matching conditions and maximize the nonlinear overlap integral. In this work, a scheme is proposed to achieve waveguide mode conversion based on 2D ferroelectric domain engineering in the emerging integrated photonic material platform of thin-film lithium niobate (TFLN), where the longitudinal periodic distribution of the second-order nonlinearity ensures the quasi-phase-matched frequency conversion between the guided-modes; while the transverse distribution can maximize the nonlinear overlap integral. As a proof-of-principle experiment, a nonlinear waveguide is designed and fabricated with 2D ferroelectric domain structure on a Z-cut TFLN, and demonstrates the conversion from TM<sub>00</sub> mode of the fundamental wave to TM<sub>10</sub> mode of the second harmonic wave. Efficient nonlinear conversions from TM<sub>00</sub> mode to high-order modes are numerically verified. The proposed nonlinear guided-mode conversion scheme has the advantages of flexible design, high conversion efficiency, and scalability, and will lay the foundation for the development of classical and quantum photonic chips with multiple degrees of freedom.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"32 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143893658","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 to transformation optics cloaks, metasurface cloaks have become the prevailing approach due to their superior ability to manipulate electromagnetic waves and their ease of fabrication. However, existing dynamic camouflage active cloaks are constrained by narrow bandwidths resulting from the nonlinear effects of lumped elements, presenting significant challenges for effective concealment under broadband detection systems. To overcome this challenge, a novel quasi-3D microfluidic dynamic camouflage cloak based on multi-physical field analysis and integration of solid and liquid metals is proposed, which can not only camouflage different real objects in the broadband range but also achieve complete filling and fast switching of large-scale two-phase microfluidics. The electromagnetic and fluidic properties of the designed cloak are validated by experiments, which agree very well with numerical simulations. This work presents a feasible broadband dynamic camouflage strategy, which is closer to practical applications, and provides unprecedented potential for near-field and far-field regulation of broadband electromagnetic waves.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"95 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143893651","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}

Finite‐Difference Time‐Domain (FDTD) simulations and the polarized photoluminescence tests confirmed that the photons entering in the pattern film can exhibit polarization characteristics, under the influence of a dielectric field originating from the periodical pattern structure. The polarization‐dependent transient absorption tests simultaneously confirmed that the carrier movement occurring in the patterned CsPbBr<jats:sub>3</jats:sub> QDs film exhibits anisotropy. For the first time, the synergistic effect of the periodic dielectric field and carrier movement anisotropy on the polarized photodetector is reported.

In this study, a straightforward and efficient approach is presented to generate powerful optical vortices directly from a thin‐disk regenerative amplifier without the need for specially designed elements for optical amplitude and phase modulations. The amplifier generates 15.8‐ps vortex pulses with an average power of 100 W and a pulse energy of 1 mJ at a repetition rate of 100 kHz, representing the highest average power of ultrafast vortex pulses ever obtained directly from an intracavity laser system to date. The demonstrated source combines, for the first time at vortex mode, a high power, a high repetition rate, and pulse energy. In addition, flexible control of the Laguerre–Gaussian, Hermite–Gaussian, and Gaussian modes is achieved within the same resonator by precisely controlling the position of the depletion area within the pump region. This work demonstrates a scalable, robust method for generating high‐power, high‐energy ultrafast vortex pulses at high repetition rate, expanding the potential applications of vortex laser technologies in both science and industry.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"20 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143893388","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 advent of three‐dimensional structured illumination microscopy (3D‐SIM) greatly benefits the biology community, providing a powerful tool for imaging organelles with a twofold resolution enhancement in all three dimensions. However, the axial resolution of 3D‐SIM is limited to around 300 nm, which is inferior to its lateral resolution. Here, a novel method called image interference SIM () is reported, which utilizes two oppositely positioned objectives to detect fluorescence emission interference under three‐beam excitation. By incorporating spectral modulation and spatial domain Frobenius‐Hessian optimization, achieves an axial resolution approximately twice that of 3D‐SIM, reaching around 130 nm. Furthermore, the potential of for imaging subcellular structures is demonstrated on various biological samples, including microtubules, actin filaments, and mitochondrial outer membranes.

Here the enhancement of PAM image quality for 3D microscopy is aimed by achieving high resolution over a large DOF, accurately restoring object sizes, and minimizing artifacts introduced during image acquisition. A novel approach is proposed that initially acquires 3D PAM images with a large DOF but low resolution through loose light focusing, and subsequently enhances resolution and image quality using a deep learning network termed LDHR‐Net. This network is trained on synthetic low‐resolution and high‐resolution image pairs generated using a physical Gaussian beam model, which accounts for depth‐dependent blurring. Application of the proposed model to experimentally acquired phantom data demonstrates significant improvements, achieving lateral resolution of ≈4 µm across an unprecedentedly large DOF of ≈4.5 mm, a 25‐fold increase compared to the intrinsic DOF (≈0.18 mm) of a PAM system with the same lateral resolution. The model's effectiveness and robustness are further validated qualitatively and quantitatively on in vivo microvasculature structures, including those in the mouse ear, back, and brain.
