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

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 ...

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 ...

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 ...

Key Laboratory of Optoelectronic Materials and Devices, Institute of Semiconductors, Chinese Academy of Sciences, Beijing 100083, China Center of Materials Science and Optoelectronics Engineering, ...

Abstract: This paper analyses electromagnetic (EM) wave propagation within a metasurface-cladded waveguide filled with magnetized plasma. First, an analytical model is developed to understand the ...

This study investigated a high-sensitivity glycerol concentration sensor based on double Fano resonances in a metal-insulator-metal (MIM) waveguide structure, established a coupling model of a baffle ...

In this work we detail the design of a novel, hybrid waveguide structure which enables independent control of phonon modes and optomechanical driving forces, thereby yielding customizable Brillouin ...
