  author={Ioana Cozmuta and Solenn Cozic and Marcel Poulain and Samuel Poulain and Jose R. L. Martini},
Materials power key technological advancements in areas such as communications, consumer electronics, aerospace, automotive and energy. Silica has become the status quo because of its abundance and affordability. Advances in areas such as quantum computing, AI and IoT will require new materials with performance envelope beyond the traditional (i.e. global internet data is rapidly growing beyond petabytes/s/km). A long-time competitor to silica, heavy metal fluoride glasses represent an… 

Absorption and multi-phonon quenching in nanocrystal doped SiO2 fibers

SiO2 fibers doped with rare-earth-doped nanocrystals are promising to overcome the strong SiO2 multi-phonon quenching and could yield novel laser gain materials. So far, no attention has been paid to

Beyond the Average: Spatial and Temporal Fluctuations in Oxide Glass-Forming Systems.

Atomic structure dictates the performance of all materials systems; the characteristic of disordered materials is the significance of spatial and temporal fluctuations on

Connecting SPHERE and CRIRES+ for the characterisation of young exoplanets at high spectral resolution: status update of VLT/HiRISE

New generation exoplanet imagers on large ground-based telescopes are highly optimised for the detection of young giant exoplanets in the near-infrared, but they are intrinsically limited for their

Grating Inscription Into Fluoride Fibers: A Review

First demonstrated over four decades ago, fiber gratings, and in particular fiber Bragg gratings (FBGs), have become indispensable and ubiquitous components within fiber laser cavities as well as

New approach for high reliability, low loss splicing between silica and ZBLAN fibers

In the past decade, ZBLAN (ZrF4-BaF2-LaF3-NaF) fibers have drawn increasing interest for laser operations at wavelengths where Fused Silica-based (SiO2) fibers do not perform well. One limitation to

Cascaded mid-IR supercontinuum generation in chalcogenide microstructured optical fibers from 2 to 10 μm

Compared to oxide based glasses, vitreous materials composed of chalcogen elements (S, Se, Te) show large transparency windows in the infrared. Indeed, chalcogenide fibers can be transparent from the

Fiber Optic Communication Systems

Understanding fiber optic transmission systems requires a knowledge of the characteristics of optoelectronic transmitters and receivers, which do not differ much from traditional copper pairs (choice of analog to digital modulation, total attenuation, etc.).

Thulium pumped mid-infrared 0.9-9μm supercontinuum generation in concatenated fluoride and chalcogenide glass fibers.

A novel approach for generating Mid-InfraRed SuperContinuum (MIR SC) by using concatenated fluoride and chalcogenide glass fibers pumped with a standard pulsed Thulium laser is theoretically demonstrated.

Scaling all-fiber mid-infrared supercontinuum up to 10 W-level based on thermal-spliced silica fiber and ZBLAN fiber

We demonstrate an integrated all-fiber mid-infrared (mid-IR) supercontinuum (SC) source generated by a 1.95 μm master oscillator power amplifier system and a single-mode ZBLAN

1.2-15.2  μm supercontinuum generation in a low-loss chalcohalide fiber pumped at a deep anomalous-dispersion region.

The broadest SC spectrum reported in any selenium-based chalcogenide fiber, ∼1.2 to 15.2 μm, was achieved by pumping a 12-cm-long fiber with a femtosecond laser at a deep anomalous-dispersion region to demonstrate spectral evolution along the fiber.
