Summary: In this study, a method for fabricating electrically conductive copper patterns and films of arbitrary topology using improved laser-induced synthesis was developed. The efficiency of the process was significantly increased through acceptor substrate pretreatment, auxiliary glass substrates, and optional laser post-processing. The potential of laser-induced periodic surface structures for tuning functional properties of the tracks was also observed.

Summary: Laser direct writing (LDW) is a promising method for fabricating metallic micropatterns on transparent substrates for transparent electronic circuits. This study proposes a novel approach called SPA-FsLDW, utilizing a femtosecond laser to achieve highly-efficient photothermal reactions through single-photon absorption by photosensitive particles. The dispersed photosensitive particles act as multiple heating sources, enabling simultaneous photothermal reactions and efficient metal ion reduction. The new approach demonstrates improved efficiency and electrical resistivity compared to previously reported methods.

Summary: Chiral nanostructures in glass can exhibit polarization-selective optical properties, which can be controlled using femtosecond laser direct writing. A phenomenological model based on two-layers phase shifters has been proposed to explain laser-induced optical chirality in initially achiral materials. This model allows for optical rotation in silica glass with the highest value reported in glass to date, providing new opportunities for photonics applications.

Summary: This study demonstrates the generation and detection of Scholte waves inside polystyrene microparticles using experimental analysis and COMSOL simulation. Different sizes of microspheres were optically excited and the acoustic signals were detected. The results obtained from the experimental and COMSOL analysis show close agreement in both time and frequency domain. The theoretical wave velocity of the Scholte wave was calculated and found to be close to the experimental results. A representation of pressure wave motion showing the Scholte wave generation is presented at different times.

Summary: This study explores the topological rotated Weyl physics in a 3D parameter space based on quaternary waveguide arrays on lithium niobate-on-insulator chips. By experimentally constructing arbitrary interfaces between two Weyl structures with freely rotated orientations, it is found that the existence of gapless topological interface states depends on the relative rotational directions of the two Weyl structures.

Summary: The field of topological photonics has seen rapid development in the past decade, achieving significant breakthroughs in controlling light behavior and triggering exotic topological phenomena exclusive to photons by engineering topologically induced interface states. By connecting two component superlattices of distinguished topological phases through a unique design, precise manipulation of spin-dependent topological interface states can be achieved, which can be straightforwardly manifested through transmission spectra. These topological interface states, deemed as a topological effect and named as secondary topological interface states, originate from the hybridization of artificial photonic orbitals of topological origin, providing an innovative and productive strategy for tuning topologically protected localized modes. Multiple applications such as selective local enhancement can be explored based on this strategy.
