Impact of optical noises on coded Brillouin optical time-domain analyzers

Luc Thévenaz, Zhisheng Yang, Sheng Wang, Jian Wu

The impact of optical noises on the performance of coded Brillouin optical time-domain analyzers is modelled and experimentally demonstrated. This enables quantitatively evaluating the actual coding gain at any point along the sensing fiber. ...

Comportement des éléments en béton armé fléchis sous charge cyclique

For various types of civil structures such as bridges, skyscrapers and other slender towers, oil rigs as well as runaways, dynamic loading is predominant. This holds true especially for bridges where loads have increased considerably in the last hundred ye ...

Multipole interplay controls optical forces and ultra-directional scattering

Olivier Martin, Karim Achouri, Andrei Kiselev

We analyze the superposition of Cartesian multipoles to reveal the mechanisms underlying the origin of optical forces. We show that a multipolar decomposition approach significantly simplifies the analysis of this problem and leads to a very intuitive expl ...

Precision Positioning of Microrobots for Multi-Object Spectrographs

Luzius Gregor Kronig

How does one study the evolution of the Milky Way, or the expansion of the Universe, or explore the mysteries of Dark energy? To investigate these complex topics, astronomers require data, and a great deal of it, in the form of the spectra of stars, galaxi ...

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 ...

Mode interference and UV-induced mode conversion in few-mode fibers

Soham Basu

Resonant and non-resonant effects in few-mode fibers have found use in versatile devices. From sensing perspective, extensive research has been done on fringe sensitivity of nonresonant two-mode interference. Resonant mode converter gratings are promising ...

Reducing Amplified Spontaneous Emission Threshold in CsPbBr3 Quantum Dot Films by Controlling TiO2 Compact Layer

Mohammad Khaja Nazeeruddin

Amplified spontaneous emission (ASE) threshold in CsPbBr3 quantum dot films is systematically reduced by introducing high quality TiO2 compact layer grown by atomic-layer deposition. Uniform and pinhole-free TiO2 films of thickness 10, 20 and 50 nm are use ...

Facile Fabrication of Microfluidic Chips for 3D Hydrodynamic Focusing and Wet Spinning of Polymeric Fibers

Fabien Sorin, René M. Rossi, Efe Armagan, Claudio Toncelli, Akin Gürsoy

Microfluidic wet spinning has gained increasing interest in recent years as an alternative to conventional wet spinning by offering higher control in fiber morphology and a gateway for the development of multi-material fibers. Conventionally, microfluidic ...

Controlling spatiotemporal nonlinearities in multimode fibers with deep neural networks

Demetri Psaltis, Navid Borhani, Eirini Kakkava, Babak Rahmani, Ugur Tegin

Spatiotemporal nonlinear interactions in multimode fibers are of interest for beam shaping and frequency conversion by exploiting the nonlinear interaction of different pump modes from quasi-continuous wave to ultrashort pulses centered around visible to i ...
