Brillouin scattering in gas-filled hollow-core fibres

Flavien Gyger

Edward E. Hagenlocker and William G. Rado demonstrated Brillouin interaction in gas for the first time in 1965, right after the very first demonstrations of stimulated Brillouin scattering in solid materials. In their experiment, they used a megawatt pulse ...

Observation of Stimulated Brillouin Scattering in Silicon Nitride Integrated Waveguides

Luc Thévenaz, Tobias Kippenberg, Rui Ning Wang, Junqiu Liu, Arslan Sajid Raja, Jijun He, Flavien Gyger

Silicon nitride (Si3N4) has emerged as a promising material for integrated nonlinear photonics and has been used for broadband soliton microcombs and low-pulse-energy supercontinuum generation. Therefore, understanding all nonlinear optical properties of S ...

Opto-mechanical cross-talk reduction in air-holes multicore fibers

Luc Thévenaz, Zhisheng Yang, Simon Adrien Zaslawski, Yun Fu

We report on the use of air-holes in multicore fibers to alleviate intercore perturbations induced by forward stimulated Brillouin scattering. Comparisons with conventional multicore fibers show significant improvement in terms of cross-talk reduction. ...

Large Brillouin Interaction in Hollow Core Fibers

Luc Thévenaz, Flavien Gyger

Brillouin gain is observed in hollow core fibers filled by standard gases at high pressure. This enables all interactions based on stimulated Brillouin scattering to be realized in hollow core fibers, such as amplification, optical signal processing and di ...

Distributed analyses using distinct classes of Brillouin scatterings in optical fibres

Desmond Chow Ming Chia

Brillouin scattering is an interaction between light and sound in a material. This inelastic light scattering had been observed in the first optical fibres that were used in cross-continent communication. Via Brillouin scattering, the guided light wave in ...

Ultra-wide-band structural slow light

Romuald Houdré, Vincenzo Savona, Momchil Minkov, Mohamed Sabry Abdel-Aliem Mohamed

The ability of using integrated photonics to scale multiple optical components on a single monolithic chip offers key advantages to create miniature light-controlling chips. Numerous scaled optical components have been already demonstrated. However, presen ...

Light Confinement and Nonlinear Light-Matter Interaction in Semiconductor Photonic Crystal Cavities

Mohamed Sabry Abdel-Aliem Mohamed

The ability to control and manipulate light is a fundamental aspect that is at the very core of the development of integrated photonic circuits. It is desirable to achieve such control down to a scale that is comparable to or smaller than the wavelength of ...

Mid-infrared continuous-wave parametric amplification in chalcogenide microstructured fibers

Camille Sophie Brès, Davide Grassani, Svyatoslav Kharitonov, Sida Xing

The persistent growth of interest in the middle infrared (MIR) is stimulating the development of sources and components. Novel waveguides and fibers for the efficient use of nonlinear effects in the MIR are being intensively studied. Highly nonlinear silic ...
