Photothermal spectroscopy on-chip sensor for the measurement of a PMMA film using a silicon nitride micro-ring resonator and an external cavity quantum cascade laser
Laser-based mid-infrared (mid-IR) photothermal spectroscopy (PTS) represents a selective, fast, and sensitive analytical technique. Recent developments in laser design permits the coverage of wider spectral regions in combination with higher power, enablin ...
Berlin2024Hybrid lithium niobate-on-silicon nitride platform for mid-IR supercontinuum generation
Tobias Kippenberg, Mikhail Churaev
Integrated optics has shown itself very convenient for exploiting nonlinear processes as it results in high confinement factor, freedom of dispersion engineering and compactness. However, the choice of materials is crucial for the development of nonlinear ...
SPIE-INT SOC OPTICAL ENGINEERING2023Observation of SQUID-Like Behavior in Fiber Laser with Intra-Cavity Epsilon-Near-Zero Effect
Camille Sophie Brès, Marco Clementi, Jiaye Wu, Qian Li, Xuanyi Liu
Establishing relations between fundamental effects in far-flung areas of physics is a subject of great interest in the current research. Realization of a novel photonic system akin to the radio-frequency superconducting quantum interference device (RF-SQUI ...
WILEY-V C H VERLAG GMBH2022Tunable 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 ENGINEERING2022Supercontinuum generation in silicon nitride (Si_3N_4) waveguides for middle infrared spectroscopy
The middle-infrared (mid-IR) spectral range hosts the most intense roto-vibrational absorption lines of many important molecules. Particularly, mid-IR spectroscopy constitutes a unique tool for identifying and quantifying molecular species through their mi ...
EPFL2021Recent advances in superconducting nanowire single-photon detector technology for exoplanet transit spectroscopy in the mid-infrared
The Origins Space Telescope mission concept includes an exoplanet transit spectrometer that requires detector arrays with ultrahigh pixel-to-pixel stability. Superconducting nanowire single-photon detectors, or SNSPDs, have the potential to meet these stri ...
SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS2021Molecular 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 ...
2020Ring a ring o' pulses
Quantum cascade lasers are bright and compact semiconductor lasers that emit light in the mid- to far-infrared spectral region. The use of a closed ring cavity has now set them on the path towards ultrafast pulses. ...
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. ...
2020System and method for a retinal projector based on a scattering reflector
Demetri Psaltis, Christophe Moser
A retinal projector system, comprising a coupling means, a spacial light modulator, and a tapered optical waveguide having an input side surface and an output side surface, whereby the input side surface is larger than the output side surface, the coupling ...
