AB Optical gas sensing for environmental monitoring has become an active research topic inthe last decade. Among the different optical sensing configurations, silicon photonicintegrated sensors stand as a compact, CMOS-compatible alternative. However, evensmall on-chip reflections can create significant fringes when the optical path length isvaried, e.g., when the wavelength is swept for TDLAS-like measurements. These fringescan be critical for NIR sensors, as absorption signals are much weaker in this region thanin the MIR. Here, we propose a signal-processing method based on minimum phasetechniques: by increasing the measurement bandwidth to around 2 nm we cancompletely remove the reflection artifacts through processing.
