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 ...

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 ...

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 ...

Birefringence is also an important issue for optical waveguides, and this property is proportional to the anisotropic ratio for the copolymer system. 23 On the one hand, the crank and twisted non ...
