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…
Balanced photodetectors nonlinearity for short-pulse regime
Philippe Guay, Jérôme Genest
Short pulse lasers are used to characterize the nonlinear response of amplified photodetectors. Two widely used balanced detectors are characterized in terms of amplitude, area, br…
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…
Amplified noise nonstationarity in a mode-locked laser based on nonlinear polarization rotation
Carlos Andres Perilla Rozo, Philippe Guay, Jean-Daniel Deschênes +1
Beat note measurements between a mode-locked and a continuous-wave laser as well as between two mode-locked sources were used to demonstrate that the sub-threshold, cavity filtered…
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…
