Nanophotonic supercontinuum-based mid-infrared dual-comb spectroscopy

Luc Thévenaz, Tobias Kippenberg, Camille Sophie Brès, Wolfgang Hänsel, Hairun Guo, Junqiu Liu, Wenle Weng

High resolution and fast detection of molecular vibrational absorption is important for organic synthesis, pharmaceutical processes, and environmental monitoring, and is enabled by mid-infrared (mid-IR) laser frequency combs via dual-comb spectroscopy. Her ...

Nanophotonic supercontinuum based mid-infrared dual-comb spectroscopy

Luc Thévenaz, Tobias Kippenberg, Camille Sophie Brès, Wolfgang Hänsel, Hairun Guo, Junqiu Liu, Wenle Weng

We demonstrate a broadband mid-infrared dual-comb spectroscopy for parallel gas-phase detection in the functional group region from 2800–3600 cm−1, using dispersion engineered silicon nitride dual-core waveguides which produce broadband, intensity-enhanced ...

Nanophotonic Supercontinuum-Based Mid-Infrared Dual-Comb Spectroscopy

Luc Thévenaz, Tobias Kippenberg, Camille Sophie Brès, Wolfgang Hänsel, Hairun Guo, Junqiu Liu, Wenle Weng

An optically stabilized dual-comb system at telecom wavelength is used to drive a mid-infrared spectroscopy for parallel gas-phase detection in the functional group region from 2800-3600 cm -1 . A coherent broadband intensity-enhanced spectrum in the mid-i ...
