Linear detection of 30 mW dual-comb interferograms
Philippe Guay, Mathieu Walsh, Alex Tourigny-Plante +1
Detector nonlinearity is an important factor limiting the maximal power and hence the signal-to-noise ratio (SNR) in dual-comb interferometry. To increase the SNR without overwhelm…

Addressing asymmetric Fano profiles on molecular lines in dual-comb spectroscopy
Philippe Guay, Mathieu Walsh, Jérôme Genest
Fano resonance in molecular spectroscopy is reported with a dual-comb instrument. The effect is observed as asymmetric absorption lines of H12CN. Pulse chirping conditions in the g…
