Laser-Induced Forward Transfer of Functional Microdevices
Laser-induced forward transfer (LIFT) technique is an emerging micro additive manufacturing (AM) technique that has been widely used to print a variety of materials. Distinguished from other nozzle-based AM techniques, LIFT operates without the existence o ...
EPFL2023Tunable wavelength-stabilized mode-locked thulium-doped fiber laser beyond 2000nm
Camille Sophie Brès, Moritz Bartnick, Gayathri Bharathan
We demonstrate operation of a tunable mode-locked thulium-doped fiber laser, based on a wavelength-selective chirped fiber Bragg grating (CFBG). By applying strain to the CFBG, we shift its reflection band and can thereby tune the emission-wavelength of th ...
SPIE-INT SOC OPTICAL ENGINEERING2022Glass-in-glass infiltration for 3D micro-optical composite components
Andreas Mortensen, Yves Bellouard, Jérôme Faist, Gözden Torun, Enrico Casamenti, Luciano Borasi, Mathieu Bertrand
Chalcogenide glass exhibits a wide transmission window in the infrared range, a high refractive index, and nonlinear optical properties; however, due to its poor mechanical properties and low chemical and environmental stability, producing three-dimensiona ...
2022Tailored on-chip mid-IR light generation and application for gas spectroscopy
Camille Sophie Brès, Davide Grassani, Eirini Tagkoudi
In this contribution, we present how coherent supercontinuum generation in Si3N4 waveguides enabled by fiber laser pumping can be tailored to cover part of the mid-IR spectrum and the use of such sources in spectroscopy. ...
2021Importance of Long-Range Channel Sr Displacements for the Narrow Emission in Sr[Li2Al2O2N2]:Eu2+ Phosphor
The recently discovered Sr[Li2Al2O2N2]:Eu2+ red phosphor, candidate for the next generation of eco-efficient white light-emitting diodes, exhibits excellent emission spectral position and exceptionally small linewidth. It belongs to the UCr4C4-structure fa ...
WILEY-V C H VERLAG GMBH2021Molecular Platform for Frequency Upconversion at the Single-Photon Level
Tobias Kippenberg, Christophe Marcel Georges Galland
Direct detection of single photons at wavelengths beyond 2 mu m under ambient conditions remains an outstanding technological challenge. One promising approach is frequency upconversion into the visible (VIS) or near-infrared (NIR) domain, where single-pho ...
2020Analysis of uncoated LPGs written in B-Ge doped fiber under proton irradiation for sensing applications at CERN
In this contribution, a complete dissertation concerning the behavior of a Long Period Grating (LPG) inscribed in a B-Ge co-doped optical fiber by means of an excimer laser and exposed to proton irradiation during a recent extensive campaign performed at t ...
NATURE PUBLISHING GROUP2020Low-loss SiN waveguides for efficient and broadly tunable nonlinear frequency conversion
Tobias Kippenberg, Camille Sophie Brès, Junqiu Liu, Florent Gilles Mazeas
We report on the use of low-loss Si3N4 waveguides for efficient frequency conversion tunable from the near infrared to the short-wave infrared. We achieve -15 dB conversion efficiency for 200 mW coupled pump power. ...
2020Optimized Electrolyte Loading and Active Film Thickness for Sandwich Polymer Light-Emitting Electrochemical Cells
Frank Nüesch, Roland Hany, Matthias Diethelm
Effects of ion concentration and active layer thickness play a critical role on the performance of light-emitting electrochemical cells. Expanding on a pioneering materials system comprising the super yellow (SY) polymer and the electrolyte trimethylolprop ...
2019All-fibered chalcogenide based continuous-wave parametric amplification in the mid-infrared
Camille Sophie Brès, Davide Grassani, Svyatoslav Kharitonov, Sida Xing
We demonstrate parametric amplification around 2 μm in a dispersion engineered tapered microstructured chalcogenide fiber. Almost 5 dB of signal amplification was achieved by 125 mW coupled power from a thulium-doped fiber pump laser. ...
