Summary: We report on the design, fabrication, and characterization of a Silicon Nitride (SiN)-based integrated photonic chip in which the dielectric waveguides are coupled to photodetectors integrated homogeneously into the Silicon substrate. The photonic-electronic coupling was realized by a 3D inverse tapering of SiN waveguides.

Summary: Co-packaged optics in next-generation datacenters require a novel photonic packaging substrate with high precision optical alignment and electrical connectivity, allowing assembly of multiple components and interconnection with optical fibers. Glass substrate optimization includes optical waveguides, fiber connectors, and chip interfaces, enabling surface mounted flip-chip assembly and precise alignment for photonic components and electrical integrated circuits. Evanescent coupling enables flip-chip assembly of photonic components with low interface loss, while glass waveguides can transmit light with minimal propagation loss.

Summary: This study systematically investigates the mechanism and performance of unidirectional coupling between valley photonic crystal waveguides and chiral dipole emitters. Two types of valley-interface waveguides, bearded stack with glide-plane symmetry and zigzag stack with inversion symmetry, are proposed with analytical derivation showing that the topological eigenmodes' Stokes parameters can predict directionality. Bearded valley-interface waveguide strategy is shown to achieve high efficiency of unidirectional coupling and reduce bias errors compared to the zigzag case.

Summary: The design of a spatial structure for three-dimensional crosslinked units is important for improving the mechanical properties of hydrogels. In this study, a pressure-responsive crosslinker called mGOa was developed, which achieved both low elastic modulus and high compression stress through interlayer sliding. The hydrogel crosslinked by mGOa showed significantly enhanced mechanical strength compared to other crosslinkers.

Summary: Negative-charge-biased zwitterionic nanodrugs can circulate stealthily in the blood and adhere to sialic acid abundant tumor cells in the tumor microenvironment. However, the particle size of these nanodrugs plays an important role in their interactions with biological systems. This study found that increasing the size of these nanodrugs improves their circulation and retention in tumor tissue, but decreases their internalization rate and tissue penetration.
