Chip maker STMicroelectronics (ST) has revealed details of a new generation of proprietary technologies enabling faster ...

Cards with a standard x16 slot are going to be limited to 400 Gbps of bandwidth until Intel, AMD, or one of Arm's CPU partners ships a PCIe 6.0-compatible processor. And even then, your server will ...

The physical interaction between two or more systems, also known as coupling, can give rise to ... light into one racetrack through its bus waveguide and measuring the output from the other ...

Scientists from the French research organisation CEA-Leti presented three papers at Photonics West 2025 detailing the institute’s latest R&D successes to improve chemical detection, high-speed ...

Discover the possibilities of twisted bilayer graphene as a replacement for silicon in integrated circuits and it's potential.

Sen. Ted Cruz released a database of over 3,400 National Science Foundation grants awarded towards what he deemed ...

Mode coupling and purity degradation have long challenged vortex photonics. A topological disclination lattice waveguide with dual topological protections now offers a solution, enabling robust ...

Abstract: An ultralow insertion loss (IL) and ultrahigh polarization extinction ratio (PER) single-polarization (SP) coupler based on dual-core photonic bandgap fiber (DC-PBF) with thin slab waveguide ...

Mode coupling and purity degradation have long challenged vortex photonics. A topological disclination lattice waveguide with dual topological protections now offers a solution, enabling robust ...

The need for accurate coupling between modes also now imposes a requirement for high degrees of spatial accuracy in the programming of such a device. Coupled waveguide arrays strike a midpoint in ...

Exact coupled-wave equations for anisotropic dielectric waveguides are derived, and explicit expressions for the coupling coefficients are given. The coupling coefficients for isotropic waveguides are ...
