Correcting photodetector nonlinearity in dual-comb interferometry
Philippe Guay, Nicolas Bourbeau Hébert, Alex Tourigny-Plante +2
Photodetector nonlinearity, the main limiting factor in terms of optical power in the detection chain, is corrected to improve the signal-to-noise ratio of a short-time measurement…
Understanding photodetector nonlinearity in dual-comb interferometry
Philippe Guay, Alex Tourigny-Plante, Vincent Michaud-Belleau +3
The impact of photodetector nonlinearity on dual-comb spectrometers is described and compared to that of Michelson-based Fourier transform spectrometers (FTS). The optical sampling…
Dual-comb correction with spectrally broadened fiber lasers
Philippe Guay, Alex Tourigny-Plante, Nicolas Bourbeau Hébert +4
The phase information provided by the beat note between frequency combs and two continuous-wave lasers is used to extrapolate the phase evolution of comb modes found in a spectral…
Single-frequency mid-infrared chip laser with a sub-hertz Lorentzian linewidth
Philippe Guay, Jérôme Genest, Vincent Michaud-Belleau +2
A guided-wave chip laser operating in a single longitudinal mode at 2860 nm is presented. The cavity was set in the Littman-Metcalf configuration to achieve single-frequency operat…
An open and flexible digital phase-locked loop for optical metrology
Alex Tourigny-Plante, Vincent Michaud-Belleau, Nicolas Bourbeau-Hébert +3
This paper presents an open and flexible digital phase lock loop optimized for laser stabilization systems. It is implemented on a cheap and easily accessible FPGA-based digital el…
