Anisotropy is an intrinsic property in crystals with low structural symmetry, and such well -textured materials usually show distinct electronic transport and optical properties along different lattice orientations, offering wide applications in electronic and photonic devices. As a typical low -symmetry materials, crystalline GeSe with orthorhombic structure shows large electric and optical anisotropies. In this work, we take advantage of the anisotropic mass transport and filamentary growth of Ag ions on the GeSe surface to fabricate planar memristive devices which show directional memory and transient switching phenomena. The anisotropic switching behaviors stem from the distinct morphology of metallic filaments that are directionally dependent on the mobility of ions, e.g., ions diffusing along the low -barrier direction tend to form stark conductive channels while those with low mobility only entail slim and weak dendrites, which have been clearly observed under electronic microscopy. The functionality could be utilized to mimic various synaptic events, such as long-term memory enabled by stable conductive channels and short-term memory by the spontaneous rupture of weak filaments, all implemented in one physical device. Two integration schemes based on the anisotropic devices are designed and demonstrated for different application scenarios, paving the way for its applications in multifunctional brain -inspired computing systems.

This paper presents an analytical demonstration of the possibility of realizing an innovative photonic system consisting of an I-shaped amplitude divider based on waveguides with one input line (finite waveguide) and three output lines, each comprising a semi-infinite waveguide. This configuration allows the guidance, separation and division of electromagnetic waves from a single input channel into several output channels, providing an efficient approach to the controlled manipulation of electromagnetic signals. The system exhibits a broad spectrum of applications across various fields, particularly telecommunications. By using the transfer matrix method (TMM) to study the propagation of electromagnetic waves through a 4-port system of waveguides, this theoretical approach makes it possible to accurately calculate the transmission rates T1, T2, and T3 as well as the reflection rate R. This method offers an in-depth understanding of the propagation phenomena in the system studied, thus providing crucial indications for designing and optimizing efficient and functional photonic devices. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Precise force measurement is critical to probe biological events and physics processes, spanning from molecular motor’s motion to the Casimir effect, as well as the detection of gravitational waves. Yet, despite extensive technological developments, the three-dimensional nanoscale measurement of weak forces in aqueous solutions still faces major challenges. Techniques that rely on optically trapped nanoprobes are of significant potential but are beset with limitations, including probe heating induced by high trapping power, undetectable scattering signals and localization errors. Here we report the measurement of the long-distance interaction force in aqueous solutions with a minimum detected force value of 108.2 ± 510.0 attonewton. To achieve this, we develop a super-resolved photonic force microscope based on optically trapped lanthanide-doped nanoparticles coupled with nanoscale three-dimensional tracking-based force sensing. The tracking method leverages neural-network-empowered super-resolution localization, where the position of the force probe is extracted from the optical-astigmatism-modified point spread function. We achieve a force sensitivity down to 1.8 fN Hz–1/2, which approaches the nanoscale thermal limit. We experimentally measure electrophoresis forces acting on single nanoparticles as well as the surface-induced interaction force on a single nanoparticle. This work opens the avenue of nanoscale thermally limited force sensing and offers new opportunities for detecting sub-femtonewton forces over long distances and biomechanical forces at the single-molecule ***-resolved photonic force microscopy employs the fluorescence of lanthanide-doped nanoparticles as a force probe, enabling the measurement of sub-femtonewton forces with a sensitivity of 1.8 fN Hz–1/2, approaching the thermal limit.

Many photonic and electronic devices rely on nanotechnology and nanofabrication, but DNA-based approaches have yet to make a significant commercial impact in these fields even though DNA molecules are now well-established as versatile building blocks for nanostructures. As we describe here, DNA molecules can be chemically modified with a wide variety of functional groups enabling nanocargoes to be attached at precisely determined locations. DNA nanostructures can also be used as templates for the growth of inorganic structures. Together, these factors enable the use of DNA nanotechnology for the construction of many novel devices and systems. In this topical review, we discuss four case studies of potential applications in photonics and electronics: carbon nanotube transistors, devices for quantum computing, artificial electromagnetic materials, and enzymatic fuel cells. We conclude by speculating about the barriers to the exploitation of these technologies in real-world settings.

In addition to the telecom and datacom sectors, the photonic sensing sector is one of the fastest-growing markets for photonic integrated circuits (PICs). The ability to combine complex and multifunctional passive and active elements on a single photonic chip, along with the adaptability of the technological platform to specific applications, opens up opportunities to construct various structures tailored to specific purposes. One of the most popular solutions for PIC-based sensors involves the implementation of ring resonators. Unfortunately, these structures are highly sensitive to production variations, often causing issues with the predictability and repeatability of the entire sensing system. Promising alternatives to these elements are Mach-Zehnder interferometers (MZIs), which offer lower manufacturing variability and greater design flexibility, however, at the cost of increasing the final size of the PIC chip. In this work, we present and discuss the results of modeling and designing sensors based on MZI structures on a sol-gel-derived HYPHa (SiO2/TiO2) technological platform. Sol-gel aqueous phase deposition and the possibility of direct nanoimprinting of waveguide structures enable low-cost fabrication of integrated devices with low propagation loss. The study considers the impact of changes in the refractive index resulting from partial and/or complete coverage of the sensing area with the tested substance. Selective coverage of the sensor with the tested substance, although requiring an additional manufacturing process, allows for significant improvement in sensitivity. We tested both variants in several sensing systems, designed and fabricated for three different wavelengths in the visible and near-infrared regions (633, 1310, and 1550 nm), with the maximal sensitivity of over 32000 nm/RIU for the sensor designed for 1550 nm.

Communication systems have become an integral part through the incorporation of advanced technologies. The millimeter-wave communication systems are developed using the aid of substrate technology integrated with deep learning techniques. They represent a greater leap in the field of wireless communication. Millimeter-wave frequencies range from 30 GHz to 300 GHz that have the capacity of higher data rates. Dielectric resonator antennas are used in millimetre-wave applications due to their compact size and efficiency. The antennas are designed using dielectric materials which have the capacity to resonate at particular frequencies. The performance of these antennas is improved using the substrate technology accompanied with deep learning techniques. They provide the optimum solution for integration with communication devices. The miniaturization of antennas is implemented using higher dielectric constant substrates. The complexity of the millimeter-wave is overcome using the aid of k-means optimization techniques. Thus, adaptive communication solutions help in the development of a millimeter wave communication system. Thus, the communication reliability is attained using these optimization techniques with estimating the channel conditions in real-time environments.

This paper presents a novel microring resonator (MRR)-based all-optical tunable temporal differentiator. By modulating the crystallinity of the ZnS-SiO2/Ge2Sb2Te5 (GST-SL) phase change material (PCM), the coupling regime of the MRR can be precisely adjusted, achieving a differentiation order (α) range of 0.7-1.3. Experimental validation with non-return-to-zero (NRZ) and return-to-zero (RZ) signal types demonstrates a strong alignment with theoretical models, maintaining an error margin below 7.3%, which confirms the device's high adjustability and stability. The proposed tuning mechanism enables low-energy, high-speed optical control of MRR states, contributing to optimized chip area and power consumption. Supported by the unique characteristics of the superlattice structure, this all-optical tunable differentiator offers promising potential for large-scale AI-driven photonic integrated circuits, particularly in applications such as optical analog computing, optical image processing, and optical neural networks. © 2025 SPIE.

The rapid progress in nanoelectronics demands customized materials for compact electronic devices. There is a requirement for materials with customized properties to fulfill the strict demands of swiftly advancing nanoelectronics, especially for an insulation coating with hydrophobic characteristics to avert moisture-induced issues in electronic components. This study investigates Diamond-like Carbon (DLC) film deposition via Radio Frequency Plasma Enhanced Chemical Vapor Deposition (RF-PECVD) and analyzes its suitability for nanoelectronics applications. Systematic variation of deposition parameters, particularly power level, is undertaken to explore the morphological, structural, wettability and electrical characteristics of DLC films. Findings reveal significant impacts of deposition power on film properties: increasing power level from 40 to 120 watts results in water contact angle shifts from 88° to 102°, rendering the film hydrophobic. This change is accompanied by variations in roughness from 7.5 to 12.25 nm and film thickness from 125 to 165 nm, respectively. Additionally, variations in resistivity and conductivity are observed through Hall Effect measurements, with higher deposition power leading to higher resistivity and lower conductivity. The findings highlight the critical role of deposition parameters in tailoring DLC film properties for specific nanoelectronics applications, contributing insights for optimizing DLC synthesis to enhance insulation and wettability for future nanoelectronics devices. © 2024 IEEE.
