However, it remains challenging to construct a controllable, high-quality VCSEL cavity without damaging the photoluminescence of CQDs to achieve the desired lasing characteristics. Here, high-quality CQDs with an engineered CdZnSe/ZnSe/ZnxCd1-xS core/interlayer/graded shell structure are developed to ensure excellent stability and sub-single-exciton gain threshold, facilitating the achievement of high-performance VCSEL. Subsequently, CQD VCSELs with distributed Bragg reflectors deposited on CQDs in situ by thermal evaporation are demonstrated. The proposed fabrication process not only enables precise control over the cavity structure but also a high cavity quality without compromising the optical properties of CQDs. Consequently, the developed CQD VCSEL exhibits a low lasing threshold of 58 µJ cm−2 and a high lasing quality factor up to 2395, setting a record for VCSELs based on CQDs or colloidal quantum-wells. It also demonstrates stable operation for 300 h at room temperature, corresponding to 1.08 × 108 stable lasing pulses, placing it among the most stable nanocrystal lasers reported. This work presents an effective strategy for achieving high-performance CQD-based VCSEL, which is significant for the future development towards non-epitaxial laser diodes.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"214 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640428","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 performance of NIR phosphor-converted light-emitting diodes (pc-LEDs) is constrained by limitations in efficiency and output power. In this work, the Gd3Al3Ga2O12 (GAGG)–Al2O3:Cr3+ ceramics are successfully synthesized via containerless solidification and glass crystallization methods. The Al2O3 matrix functions as an optically active component akin to GAGG, mitigating concentration quenching effects while preserving strong light absorption. Under 450 nm light excitation, the ceramic exhibits intense NIR luminescence, achieving exceptional internal/external quantum efficiencies (IQE/EQE = 96.8%/46.1%) and remarkable thermal stability (94.3%@150 °C). The ceramic-converted NIR LED (cc-LED) demonstrates outstanding photoelectric conversion efficiency (28%@350 mA) and robust NIR light output (236 mW@350 mA). Additionally, the laser diode (LD)-excited NIR device achieves an exceptional watt-level light output (1.52 W@10 W mm−2). As a proof of concept, this NIR light source shows immense potential for diverse applications including plant illumination, nondestructive testing, and bioimaging systems. Therefore, this innovative GAGG–Al2O3:Cr3+ NIR-LED&LD not only broadens the practical application scope of NIR light sources but also offers a transformative pathway for next-generation compact high-power devices in this field.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"33 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640431","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}

Here, the development of inorganic oxide glasses is demonstrated wherein the growth of plasmonic nanoparticles (NPs) based on indium tin oxide (ITO) through solid-state reaction can be manipulated in a controllable manner. The plasmonic response of the precipitated ITO NPs contributes to boosted and tunable infrared nonlinear optical (NLO) response associated with localized surface plasmon resonance (LSPR) of the ITO NPs. It is further elucidated that the plasmon coupling between ITO NPs in the glass matrix plays an essential role in the 100-fs scale NLO response by accelerating the relaxation of hot electrons, such that the NLO response speed can be enhanced to exceed that in typical noble metal-based plasmonic nanostructures. The ultrafast absorptive optical nonlinearity with a high modulation depth could enable diverse applications, as exemplified here by the robust optical switching for mode-locked pulse generation in fiber lasers. These results could have strong implications for the development of integrated solid-state plasmonic devices for photonics applications.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"69 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640432","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, traditional fractional-order OAM holography faces challenges due to significant cross-talk between adjacent channels. To address this issue, additional parameters are typically required. Here, the spiral-fractional OAM (SF-OAM) multiplexed holography with perfect OAM modes is proposed. In this method, the spiral fractional OAM modes, which differ from traditional fractional OAM, are combined with integer OAM modes to serve as independent channels for information encoding. The preservation, selectivity, and multiplexation of SF-OAM; and the 3D spatial SF-OAM multiplexing are demonstrated. Furthermore, the superposed SF-OAM beams-based holography is investigated, in which only the correct superposed beam can obtain the output image with the maximum intensity at each pixel. The experimental results are in good agreement with numerical simulations, confirming the feasibility of such scheme. This research significantly enhances the information capacity and encrypted security of optical holography.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"19 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640429","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}

An outstanding example is in vivo all-optical cancer diagnostics, which mitigates patient safety risks and economic costs of surgical tissue extraction. Recently, lensless endoscopy has enabled 3D illumination and imaging through specialty fibers with diameters of only a few hundred microns. However, it requires complex electro-optical components and sophisticated real-time calibration concepts to correct the dynamic distortions that the fibers imprint on the to-be-received images. Consequently, clinical applications have not yet been addressed. Bridging this gap, endoscopic direct and pixelation-free imaging is demonstrated via a unique optical fiber that mimics the functionality of a diffractive lens but is minimally invasive and resilient to bending. Particularly, the approach utilizes a hologram printed on the facet of a bend-resilient multicore fiber. The hologram contains a Fresnel-like phase zone plate that generates a focal plane for imaging. Additionally, a quasi-aperiodic arrangement of the fiber cores, combined with a physics-informed neural network mitigates ghost images and enhances the imaging contrast. The presented approach opens a novel pathway to translate ex vivo microscopy to in vivo endoscopy, for instance for low-risk minimally invasive diagnostics or optogenetics.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"15 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640430","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}

Here, fast-response, high-sensitivity PNPDs are demonstrated using spin-deposited polycrystalline 2D (poly-2D) Ruddlesden–Popper (RP) perovskite films with thickness of ≈3.6 µm. The strong narrowband excitonic light absorption and limited charge diffusion length of poly-2D RP perovskites enable a favored long-wavelength response and a significant suppression of short-wavelength response to further strengthen the CCN effect. In particular, the photodetection properties, as well as the spectral rejection ratio and central response wavelength, can be finely tuned with an alkyl chain length of the spacer cations. The optimized devices achieve a narrow spectral response with a full-width at half-maximum of 12.7 nm, a record high peak specific detectivity of 1.09 × 1012 Jones and ultrafast response speed with rise/fall times of 5.6/11.5 µs, which outperform the published similar PNPDs. Moreover, a spin-deposited large-area sensing array with 6 × 6 PNPDs is fabricated with high consistency, for efficient color and shape discrimination demonstrations.

In this work, the refraction mechanisms of topological edge modes at different external coupling boundaries are investigated, and demonstrate topological interconnections and switches on a chip. The reflection of topological modes refracted into slab waveguides is compared through zigzag, armchair, and vertical zigzag terminations. The vertical zigzag termination demonstrates high external coupling efficiency with a constant refraction angle at different wavelengths. Based on these findings, a compact and low-loss waveguide crossing for configurable topological interconnections. To demonstrate practical applications a compact 2 × 2 topological switch is presented that utilizes the proposed crossing and a topological Mach-Zehnder interferometer (MZI) structure is proposed.
