A petal-shaped metamaterial absorber is designed based on vanadium dioxide phase transition control and prepared metamaterial samples using surface projection micro stereolithography (PµSL) 3D printing technology. Then, vanadium dioxide thin films are coated on the surface of the metamaterial using the ultrasonic spraying method. The PµSL 3D printing technology makes it possible to prepare high-precision complex samples, and the ultrasonic spraying method enables the coating of vanadium dioxide thin films at room temperature. To demonstrate the stability of this method, two different metamaterial structures are prepared: planar structure and hemispherical structure. In the experiment, a non-contact heating method is used to regulate the temperature of the vanadium dioxide thin film, which made the temperature of the metamaterial sample controllable, stable, and uniformly heated. The experimental results show that the designed metamaterial absorber has excellent modulation performance and excellent switching characteristics, which proves the reliability of the method.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"8 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031314","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 ideal on-chip optical absorber is expected to have a superior absorption capability across a wide range of frequencies while maintaining a minimal footprint. However, widely employed optical thin-film absorbers suffer from limited absorption due to inherent refractive index mismatches and short light-matter interaction lengths. Here a ≈45-nm thin metalayer is demonstrated that exhibits uniformly high absorption over a broad wavelength range from 350 nm to 4.5 µm in a wide range of incident angles up to over 60 degrees. The metalayer's performance notably exceeds the absorption predicted by standard plane-wave optics theories, potentially attributing to the Anderson localization effect.

Due to the high-limit of doping concentration, current homogeneous ENZ materials based on heavily doped conductive oxide including ITO usually exhibit a zero-permittivity wavelength (λ0) longer than 1200 nm. Here, this is identified with combined theoretical and experimental investigations that stoichiometric rutile-type RuO2 (r-RuO2) exhibits the shortest λ0 of near 800 nm among conductive oxides, benefiting from the high free electron concentration with characteristic Drude-type response. The ENZ effect is manifested by the strong field enhancement and the large nonlinear optical (NLO) response in colloidal processed r-RuO2 nanoparticles (NPs) and thin films. By ultrafast transient spectroscopy, the strong NLO response in r-RuO2 NPs is revealed to be the result of rapid thermalization/cooling of free electrons in the strong hybridized Ru-4d/O-2p orbitals. The ultrafast optical nonlinearity is exploited further for the development of multi-purpose all-optical switches that enable stable pulse laser generation in four mode-locked and Q-switched fiber lasers.

In this work, an innovative cooperative scattering structure is introduced that combines a nanopore configuration with an aluminum (Al) nanoparticle array on the n-AlGaN layer of the DUV LEDs. The integration of these two scattering arrays can enhance light extraction by mitigating total internal reflection at the device interface. The nanopores are formed on the n-AlGaN surface by electrochemical etching and optimized by varying the etching voltage, while the Al particles are formed by thermal annealing. With the help of the cooperative scattering structure, the light output power (LOP) of the optimized DUV LEDs is significantly increased by 77.6% and a notable 2.2 times is achieved in its light extraction efficiency (LEE) enhancement factor.

It is based on sample illumination with several illumination fringe patterns featuring distinct mutual phase shifts, from which an axially sectioned image is reconstructed. Its optical sectioning capability is commonly attributed to the attenuation of the fringe modulation of light collected from planes displaced from the focal plane. However, in addition to this effect, which is governed solely by the detection optics, optical sectioning can be further enhanced by confining the fringe modulation axially via partially coherent illumination (PCI). To establish guidelines for optimal illumination field shaping, both theoretically and experimentally are investigated, the optical sectioning strength of OS-SIM upon variation of the two key parameters, modulation period and angular spectrum of the incident illumination. By using PCI with OS-SIM, nearly fivefold and 1.4-fold enhanced axial resolution have achieved for scattering (non-fluorescent) and fluorescent samples, respectively. This work elucidates the optical sectioning mechanism of OS-SIM and provides a perspective for further optimization.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"34 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026588","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}

To address these challenges, a modified MML is developed with a novel phase distribution. This modified MML exhibits significantly enhanced performances, achieving over 40% focusing efficiency across a ≈17× zoom range, an axial displacement tolerance of 40λ, a lateral misalignment tolerance of 10 units (meta-element size), and an ultra-wide operating bandwidth covering ≈40% of the central frequency. In a proof-of-concept experiment using a frequency-tunable terahertz (THz) free-electron laser, the experimental results aligned well with numerical simulations, demonstrating the exceptional performances of the modified MML in the THz band.

In accordance with the proposed interferometry, a new phase-demodulation method is experimentally demonstrated, which is operated in the domain of the OAM complex spectrum and thus enables accurate yet high efficient extraction of the phase-change information from the captured OAM interferograms. As typical results, rotational and linear displacements are simultaneously and accurately measured with accuracies of 2.89° and 16.04 nm, respectively.

However, the current photonic biosensor designs are not suitable for highly integrated and multiplexing device architectures that can achieve the detection of complex combinations of many biomarkers. Here, a topological scheme is proposed for the integration of miniature biosensors in photonic crystal chips that can meet the above requirement. Using photonic topological edge states as robust 1D waveguides that connect many photonic biosensors, here the topologically integrated photonic biosensor circuits is proposed. It is demonstrated that the performance of the topologically integrated photonic biosensors is much more robust against disorders than that of the photonic biosensors connected by the normal photonic waveguides, due to the robust transport of photons along the edge channel. Since disorders arising from the fabrication imperfection and the random distribution of the biomarkers are inevitable in genuine devices, resilience against disorders is a necessity for on-chip integration of biosensors. The topological scheme proposed here thus opens a promising path toward reliable integration of photonic biosensors for next-generation biomedical applications.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"22 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992189","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, at terahertz and higher frequencies, implementing active elements in multilayer configurations presents challenges that are not as straightforward as those encountered in the microwave range. In this work, it is demonstrated that tristate ART tuning can be realized in a single-layer, free-standing metasurface by switching between a dual dipolar mode (electric dipole and magnetic dipole) and a single dipole mode (electric dipole). By transferring a flexible vanadium dioxide (VO2) thin film onto the free-standing dielectric Huygens’ metasurface, ART modulation is achieved, transitioning from a near-unity transmission state to a near-perfect absorption state, and finally to a high-reflection state with the reflection up to 0.65 during the insulator-to-metal transition induced by heating onto the phase-change material.
