Cost-effective equalization of electro-optic frequency combs in a Sagnac interferometer
Camille Sophie Brès, Jianqi Hu, Ivan Cardea
We present a cost-effective electro-optic frequency comb generation and equalization method using a single phase modulator inserted in a Sagnac interferometer layout. The equalization relies on the interference of comb lines generated in both clockwise and ...
Optica Publishing Group2023Ultrafast Laser Direct-Writing of Self-Organized Microstructures in Ge-Sb-S Chalcogenide Glass
The structuring of mid-IR materials, such as chalcogenide glass (ChG), at the micro and nano scales, is of high interest for the fabrication of photonic devices in general, and for spectroscopy applications in particular. One efficient method for producing ...
2022In Situ Infrared Spectroscopy of NOx Reduction Catalysts: A Laboratory Exercise for In-Person and Virtual Learning
Davide Ferri, Oliver Kröcher, Rob Jeremiah G. Nuguid
Infrared (IR) spectroscopy and catalysis represent two of the most practically relevant topics in chemistry, but they are normally taught in separate contexts at the undergraduate level. Although IR spectroscopy is introduced to students as a tool for orga ...
AMER CHEMICAL SOC2022Broadband Optical Spectrum Downconversion to RF Using Integrated Dual-Comb Source
Combining all the benefits of Fourier transform infrared (FTIR) spectroscopy in a chip scale spectroscopic sensor looks promising for mobile and wearable platform development. Dual-comb spectroscopy enables downconversion of optical absorption spectra into ...

EPFL2020Parallel gas spectroscopy using mid-infrared supercontinuum from a single Si3N4 waveguide
Tobias Kippenberg, Camille Sophie Brès, Davide Grassani, Clemens Herkommer, Eirini Tagkoudi
Efficient third-order nonlinear optical processes have been successfully integrated on silicon nitride (Si3N4) waveguides. In particular, owing to Si3N4 wide transparency window spanning from the visible to the middle-infrared (mid-IR), efficient mid-IR di ...
2020Atmospheric particulate matter characterization by Fourier transform infrared spectroscopy: a review of statistical calibration strategies for carbonaceous aerosol quantification in US measurement networks
Satoshi Takahama, Mária Lbadaoui-Darvas, Matteo Reggente, Charlotte Marie Bürki, Adela Kuzmiaková
Atmospheric particulate matter (PM) is a complex mixture of many different substances and requires a suite of instruments for chemical characterization. Fourier transform infrared (FT-IR) spectroscopy is a technique that can provide quantification of multi ...
2019Two-Dimensional Conical Dispersion in ZrTe5 Evidenced by Optical Spectroscopy
Zirconium pentatelluride was recently reported to be a 3D Dirac semimetal, with a single conical band, located at the center of the Brillouin zone. The cone's lack of protection by the lattice symmetry immediately sparked vast discussions about the size an ...
