Summary: In this study, single-crystalline aluminum nanowires with high stability were fabricated using a superplastic nanomolding technique. These nanowires exhibit multimode waveguiding, efficient beam splitting based on polarization, and durable thermal optical modulation, making them suitable for nanophotonic routers, splitters, and information encryptors. This technique can also be extended to other metals, enhancing the development of functional nanophotonic devices and integrated optical chips.

Summary: In this study, ion-exchanged optical waveguides were fabricated based on low-cost soda-lime glasses embedded with silver ions and nanoparticles. The ion-exchanged glasses showed low-loss properties and were characterized using various techniques. It was found that using an Ag-AgCl layer on the waveguide was an effective method for coupling light and measuring its refractive index. This combination of techniques served as an excellent platform for integrated optical circuits.

Summary: By bending 2D materials into parabolic shapes to form waveguides, the field confinement associated with graphene plasmons can be significantly increased, leading to the formation of plasmonic waveguides. In 2D parabolic waveguides, the high field confinement of channel polaritons can enhance the spontaneous emission rate of quantum emitters near the parabolic vertex.

Summary: Subwavelength grating (SWG) metamaterial waveguides and ring resonators on a silicon nitride platform are proposed and demonstrated. The SWG waveguide achieves a large overlap (53%) of the Bloch mode with the top cladding material, showing great potential for evanescent field sensing and light amplification. Fabricated using a commercial rapid turn-around silicon nitride prototyping foundry process, the devices have critical dimensions greater than 100 nm. Experimental characterization reveals excellent internal quality factor (2.11 x 10(5)) and low propagation loss (approximately 1.5 dB cm(-1)) in the C-band, surpassing silicon-based SWG ring resonators. These results demonstrate the promising prospects of SWG metamaterial structures for silicon nitride based photonic integrated circuits.

By using molecular crowders, ordered bundling of DNA filaments and formation of ring-like cortical structures similar to actin rings during cell division were achieved. Additionally, DNA filaments were programmably linked to the compartment periphery using cholesterol-tagged DNA and were able to deform GUVs from within.

Summary: Hot electron photocatalysis is a fascinating field with great technological potential. However, the mechanisms behind it are not fully understood. In this study, we propose a mechanism based on transient electron spillover and energy release into vibrational modes. Using real-time Time Dependent Density Functional Theory, we simulate the dynamics of hot electrons moving on chains of Ag or Au atoms with different adsorbates. Our results show that specific modes are selectively activated, and the energy transfer depends on the adsorbate, metal, and hot electron energy. This mechanism could play a significant role in hot electron photocatalysis.

Summary: This article presents a machine learning algorithm that can identify chemicals by matching their SERS spectra to a standard Raman spectral library. The algorithm uses a facial recognition-like approach for spectral recognition and quantifies the degree of similarity to a Raman spectrum using a metric called Characteristic Peak Similarity (CaPSim). The analysis shows that CaPSim outperforms existing spectral matching algorithms in terms of accuracy. This machine learning-based approach could greatly facilitate the spectroscopic identification of molecules in fieldable SERS applications.

Summary: This research successfully demonstrates the generation and direct sampling of ultra-broadband infrared laser pulses at a high repetition rate (about 80 MHz) with stable carrier-envelope phase, possessing a spectral bandwidth of 1.1 octaves. By performing electron tunneling current measurements on a chip, the electric field of the laser pulses can be sampled in an ultra-broadband manner. This result paves the way for broad applications in near-field ultrafast spectroscopy and on-chip light-wave electronics.
