Towards a Dual-Comb Spectrometer on a Photonic Chip (ETh2A.1)
Presenter: Nathalie Picqué, Max-Planck-Institut fur Quantenoptik

Dual-comb spectroscopy emerges as a powerful tool for laboratory and field spectroscopy. The progress toward ultra-miniaturized instruments using electro-optic modulators or semi-conductor mode-locked lasers on photonic chips will be illustrated and discussed.

Porous Silica Enrichment Films on Integrated Waveguides for Broadband Mid-IR Spectroscopic Trace Analysis (ETh2A.4)
Presenter: Bettina Baumgartner, Technische Universität Wien

Germanium-on-Silicon waveguide chips coated with functionalized mesoporous silica were used for evanescent wave sensing of organic contaminants in gas and aqueous phase. Low ppm level LODs and fast response times pave the way for in-line monitoring.

Mid-infrared methane sensing using interband cascade laser and anti-resonant hollow-core fiber (ETh2A.5)
Presenter: Grzegorz Gomolka, Wroclaw University of Science and Technology

Mid-infrared laser absorption spectroscopy of methane near 3.27 µm inside hollow-core fiber is presented. High sensitivity and selectivity are obtained by using wavelength modulation spectroscopy method and interband cascade laser as a source.
