Cooling from room temperature to 78 K increases the peak absorption cross sections in the pump band at 486 nm in the cyan‐blue significantly and the peak emission cross sections in the yellow by a factor of five, while slightly increasing the fluorescence lifetime. An improved growth procedure of the laser crystal enables an increased room‐temperature slope efficiency of 36% at 587.4 nm. At 100 K, slope efficiencies of up to 61% are obtained and optical‐to‐optical efficiencies of 55% at a wavelength of 581.4 nm, doubling all values previously reported for yellow Tb<jats:sup>3+</jats:sup>:LiYF<jats:sub>4</jats:sub> lasers and establishing this system as the most efficient yellow laser source to date. During these experiments, continuous‐wave laser operation at 624 nm is realized as well with a slope efficiency of 47% at 78 K. The study enhances the understanding of the processes currently limiting the room‐temperature performance of Tb<jats:sup>3+</jats:sup> lasers, which facilitates improved laser performance by tailored gain materials even in the temperature range accessible to Peltier cooling.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"8 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143875986","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 resulting organic–inorganic nanoconjugates are able to integrate individual strengths and show exciting optical/electrical/magnetic functionalities. However, there is a shortage of systematic reviews reporting the most recent progress of interfacial molecular engineering of RE NCs. Thereby, this review presents a comprehensive and timely perspective on recent advances in interfacial molecular engineering of RE NCs. The crucial theoretical knowledge is first summarized, ranging from the luminescence mechanism of organic molecules/RE NCs to the energy transfer mechanisms at the organic–inorganic interface. Construction protocols for coupling organic molecules and RE NCs are then discussed, including chemical coordination and physical adsorption pathways. In particular, beyond traditional bio-imaging/therapy, advanced applications of RE NCs enabled by interface molecular engineering are outlined, not limited to photoexcited 3D printing, light-induced photochromism/deformation, individual micro-modification, and dynamic procedure regulation. Finally, challenges and perspectives are presented to accelerate future progress and provide research guidance for the interfacial molecular engineering of RE NCs. This review provides a deeper and broader understanding of the interfacial molecular engineering of RE NC and pushes this technology closer to practical applications.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"6 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143862055","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 beam splitters, constructed with prisms or flat glass plates, are bulky and limit optical system design. Metasurfaces are artificial planar optical elements whose flatness and compactness facilitate optoelectronic integration with semiconductor devices, resulting in the development of miniaturized and multifunctional optoelectronic devices. Here, multifunctional beam splitters are proposed that monolithically integrate metasurfaces with a standard vertical cavity surface-emitting lasers (VCSELs). By engineering the phase profile, the device can achieve various beam-splitting functions, including a polarization-insensitive high-efficiency power splitter, a multi-channel power splitter, and a polarization power splitter. Experimental results show that the measured splitting ratios (SRs) of the polarization-insensitive power splitters are as follows: 0^th to -1^st order ranges from 0.92 to 70, and -1^st to -2^nd order ranges from 0.01 to 80. The multi-channel power splitter exhibits SR of 6.6:4:3:1 for the -1^st and +1^st orders in the x and y directions. The polarization power splitters enable tunable SRs for ±1 orders, ranging from 0.06 to 1.1. This on-chip integration of power beam splitter is believed has promising potential to drive the development of new compact optical systems and advance integrated photonic applications.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"2 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143862079","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}

Balancing these characteristics remains a challenge. Developing broadband infrared detection that achieves high responsivity while maintaining high-speed operation at room temperature is a key objective for the next generation of infrared sensing technologies. In this work, a novel 2D/organic hybrid photogating field-effect transistor (PVFET) capable of broadband detection spanning 488–1550 nm is reported. This device simultaneously enhances both gain and response speed, achieving a remarkable gain-bandwidth product of 1.18 × 10¹⁰, thereby overcoming the conventional trade-off between responsivity and speed. Through comprehensive analysis of the device's physical dynamics, the correlation between PVFET performance, incident wavelength, and device Fermi level is demonstrated.

The manipulation of laser spatial modes has emerged as an advanced technique for expanding encoding dimensions. However, relying exclusively on mode orders as the encoding dimension in mode-division multiplexing (MDM) still limits the potential for improving encryption security. In this study, multidimensional optical encryption is achieved by manipulating elliptical orbital angular momentum (OAM) modes within microlasers. By governing the photonic orbits in a Fabry–Pérot (FP) microcavity, four independent optical dimensions are established within a single elliptical OAM mode: azimuthal order, radial order, ellipticity, and long-axis direction. This configuration enables 4D encryption through the construction of a microcavity array. Moreover, the distinct laser patterns provide the microcavity array with a physical unclonable function (PUF), which further enhances the security level of the encryption device. This study presents a strategy for increasing the multiplexing capacity in microlasers, offering promising platforms for high-security optical encryption and anticounterfeiting.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"12 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143862086","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 coupling of 2D magnetic order with electrons, phonons, and photons can profoundly influence the physical properties of 2D magnets, leading to advancements in spintronics and optoelectronics. However, the practical application of 2D magnets is impeded by the air-instability and inadequate understanding of the complex coupling effects associated with 2D magnetic ordering. A study is presented here on the temperature, wavelength, and field-dependent photoluminescence (PL) spectra of one of the few air-stable van der Waals magnet CrPS₄. A notable decreasing of the dominant PL peak intensity is observed in the presence of magnetic order and external magnetic field. Combined with theoretical calculations, this study determines that the modulation of PL intensity by magnetic order stems from the spin-restricted selection rule imposing on the electron–hole radiative combination, resulting in the darkening of the bright excitons. Since spin-polarized electronic band structure is prevalent in 2D magnets, these findings unveil a universal spin-charge coupling effect and offer valuable insights into the fascinating interplay between magnetism and optical properties in 2D magnets, advocating strong promises for the development of advanced magneto-optoelectronic devices based on CrPS₄.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"125 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143853757","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 proposed ADMN is composed of three sub-metalenses simultaneously working for 0°/90°, 45°/135° linear polarization (LP), and left/right-handed circular polarization (L/RCP), respectively, from which the full Stokes polarization images can be obtained. Simultaneously, the 3D images of the object can be constructed by the parallaxes among different images obtained by different sub-metalenses. At the design wavelength of 532 nm, experimental results show that the averaged extinction ratios of the LP and CP of the fabricated ADMN are ≈10:1 and ≈23:1, respectively.

Here, a unique type of SMs, termed soliton molecular chains (SMCs), in a passively mode‐locked fiber laser is reported and their formation mechanism—the cascaded self‐injection trapping—is elucidated. The SMCs comprise equally spaced multi‐solitons, increasing progressively with pump strength, and exhibit temporal separation locking and relative phase correlating behaviors. Simulation results fully reproduce and interpret experimental observations, unveiling that the emerging solitons in SMCs are trapped at the local minima of the effective pinning potential in a cascade manner. Specifically, these potential wells originate from the interactions between the emerging solitons and the time‐delayed self‐injection pulses of the preceding soliton generated through an inherent sub‐cavity. Unlike SMs formed through long‐range interactions between solitons and background oscillations, this study demonstrates a novel mechanism that provides an alternative approach to synthesizing SMs with desired patterns by artificially introducing self‐injection pulses.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"45 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143853325","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}
