Digital electronics platform-based supercontinuum light detection for mid-infrared trace gas sensing
Chin, Sanghoon; Denis, Séverine; Jérôme, Van Zaen; Muntané, Enric; Amir, Khodabakhsh; Frans, Harren; Patrick, Bowen; Stephan, Schroder; Steve, Lecomte; Laurent, Balet (2022-05-15)We present a digital platform-based lock-in detection scheme to improve the gas sensing performance of a spectrometer. A numerically-controlled oscillator serves as reference clock to trigger the supercontinuum source and ... -
Digital OPLL-based distributed Brillouin sensing system in optical fibers
Chin, Sanghoon; Denis, Séverine; Kundermann, Stefan; Brasch, Victor; Lecomte, Steve (2022-05-23)A digital optical phase-locked loop (OPLL) has been implemented to develop a distributed Brillouin sensing system in optical fibers. In our experiment, two commercial semiconductor lasers are phase-locked to each other ... -
