SRS microscopy, particularly with label-free imaging capability, has become crucial in bioimaging; however, its spatial resolution remains limited by the diffraction limit, driving interest in super-resolution techniques with structured light. While recent advancements suggest promising approaches, nonlinear Raman interactions involving LG vortex beams remain underexplored. Here, the exact analytical expressions for SRS signals are derived by expanding one of the beams as a series of LG modes of the other and integrating Laguerre polynomials and product LG modes. The findings reveal that the SRS signals critically depend on the topological and hyperbolic momentum charges of the LG pump and Stokes beams. These results establish a quantitative framework for coherent Raman scattering processes induced by tailored and focused vortex beams, providing a theoretical foundation for applications in biological and material imaging as well as in the nonlinear optical detection of light's orbital angular momentum employing coherent Raman scattering measurement techniques with toroidal beams.","PeriodicalId":7263,"journal":{"name":"Advanced Photonics Research","volume":"6 7","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adpr.202400202","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144574174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the broad unregulated bandwidth, high-speed data transmissions are achieved. However, direct line-of-sight links are required in OWC systems, and typically only point-to-point or limited point-to-multi-point connections can be achieved, limiting the communication robustness and user movements. In addition, accurate alignment between transceivers is required to maintain the high-speed optical link, demanding adaptive beam control functions. To solve these constraints, the use of intelligent metasurfaces for dynamic beam steering and beam manipulation in OWCs is proposed and investigated. Such metasurfaces with sub-wavelength features also enable other versatile functions like spatial- or optical-angular-momentum-mode generation, conversion, and multiplexing, further improving the communication performance and capability of OWCs. In this article, the recent progress is summarized and the view on the possible future research directions in this emerging field that incorporates OWCs with metasurfaces is provided.","PeriodicalId":7263,"journal":{"name":"Advanced Photonics Research","volume":"6 7","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adpr.202500015","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144573407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, wavelength and frequency band of PhPs are currently quite narrow and heavily dependant on phonon reststrahlen bands of material chosen. In most cases, these reststrahlen bands cannot be fully occupied. Moreover, methods for tuning and manipulating PhPs are rather limited. Herein, an idea of curvature and dielectric is introduced to tune properties of surface phonon polaritons (SPhPs) in quasi-1-dimensional complementary nanostructures: nanowire (NW) and nanohole (NH). Numerical results of wurtzite AlN and cubic SiC show that dispersive spectrum of SPhPs can be effectively regulated by curvature and dielectric methods. NH complements frequency band range of SPhP modes of NW structures. NW together with NH accurately occupy the whole reststrahlen band of SPhPs of semiconductors. Furthermore, the frequency-band subinterval of SPhP in NHs and NWs can be significantly tuned by dielectric. The SPhP dispersion spectrum and wavelength compression ratio in NW and NH structures are inherently self-consistent. Moreover, calculated results are in good agreement with relevant experimental data. Herein, new ideas are provided for the regulation and manipulation of PhPs in nanostructures.","PeriodicalId":7263,"journal":{"name":"Advanced Photonics Research","volume":"6 7","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adpr.202400211","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144573395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To systematically investigate the influence of the resonant radiation, metamaterial-based band-pass and notch filters are fabricated to selectively transmit or reject the frequency component around 1.6 THz from the generated broadband THz spectrum for treatment. Cancer DNA samples are irradiated with high-power THz waves, with and without the use of these filters, and methylation levels are subsequently measured through enzyme-linked immunosorbent assay (ELISA) technique. Using the 1.6 THz band-pass filter, high-power THz wave irradiation significantly reduces the methylation levels of cancer DNA by at least 19% after 30 min exposure, compared to untreated samples, yielding results similar to those without spectral filtering. In contrast, applying the 1.6 THz notch filter results in negligible changes in methylation levels, underscoring the role of the cancer DNAs’ molecular resonant frequency near 1.6 THz in the decrease of the global methylation. These results suggest that high-power THz waves can effectively modulate the methylation degree in cancer DNA, presenting a promising novel approach for anticancer therapies.","PeriodicalId":7263,"journal":{"name":"Advanced Photonics Research","volume":"6 7","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adpr.202400231","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144573394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In these measurements, high-bandwidth photodetectors are normally used for signal acquisition and processing, which complicates the measurement system. QCL is well-known for its picosecond gain-recovery time with an intrinsic bandwidth of tens of GHz. In this work, a compact self-detecting dual-comb spectroscopy (DCS) is demonstrated based on dispersion-engineered, high-speed packaged QCLs under coherent injection locking. The laser source is designed and fabricated into a hybrid-monolithic-integrated waveguide and epi-down packaged on a wideband-designed submount to fully explore the high-speed feature up to fourth-order harmonic state with a cutoff frequency of 40 GHz. The effective radio frequency (RF) injection locking diminishes the issue of optical feedback and enables high-bandwidth self-detection based on QCLs. Clear and stable multiheterodyne signal corresponding to a spectral range of 68 cm−1 and narrow comb tooth linewidth of ≈10 kHz is observed without using external detector or numerical process.

Polytetrafluoroethylene (PTFE) lenses, including spherical, aspherical, and cubic geometries, are fabricated and evaluated at frequencies of 0.15 and 0.3 THz. The lenses show enhanced responsivity and reduced noise-equivalent power, with performance characteristics strongly dependent on frequency and shape. Aspherical lenses achieve superior spatial resolution at 0.3 THz, characterized by the smallest spot sizes and full width at half maximum. Although with a bigger spot size, spherical lenses show an increase of responsivity signal of a factor of 1.5 with respect to the aspherical lenses at 0.3 THz. Cubic lenses, on the other hand, exhibit significant signal strength enhancement at 0.15 THz, but not at 0.3 THz. A damping of Fabry–Pérot oscillations at higher frequencies is also observed, contributing to improved spatial resolution. These results demonstrate the potential of the terajet effect to optimize THz detection systems for diverse applications, including medical imaging, security screening, and nondestructive testing.

To take full advantage of the shorter processing laser wavelength, the addition of absorbing additives, such as carbon black nanoparticles, becomes inevitable. Many nanoparticle characteristics can influence the laser-material interaction, such as quantity, dispersion, and position relative to the polymer matrix, but have not been investigated under processing conditions. Therefore, this study improves the understanding of the optical material properties present in laser powder bed fusion by quantifying the thermo-optical properties of PA11 powder, melt and solid, additivated with minute amounts of carbon black nanoparticles on the surface and throughout the volume of the particles. Surface-additivation results in the highest increase in laser attenuation overall and creates a segregated network that acts as a barrier to laser penetration in the molten and solid state. By contrast, the random distribution of agglomerated nanoparticles throughout the particle volume allows most of the laser radiation to pass through. Other nanoparticle effects, such as thermal stabilization and crystal formation, affect the volume-additivated particles the most. The thermo-optical results are complemented by analysis of process-relevant powder, thermal, structural, and compositional material properties.","PeriodicalId":7263,"journal":{"name":"Advanced Photonics Research","volume":"6 7","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adpr.202400207","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144573207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
