Abstract Nondispersive infrared (NDIR) spectroscopy is an important technology for highly accurate and maintenance-free sensing of gases, such as ethanol and carbon dioxide. However, NDIR spectroscopy systems are currently too expensive, e.g., for co

We show detection of CO2 concentrations as low as 500 ppm using a suspended silicon photonic mid-IR waveguide. The performance is enabled by the low propagation loss (2.35 ± 0.25) dB/cm permitting sensing with waveguides up to 7 cm in length.

Optical spectroscopy is among the most important chemical analysis techniques, due to its high specificity and long-term stability. For spectroscopic analysis of gas compositions, the mid infrared (mid-IR) region is particularly important, owing to t

Air pollution is one of the largest risk factors for disease or premature death globally, yet current portable monitoring technology cannot provide adequate protection at a local community level. Within the TRIAGE project, a smart, compact and cost-e

We demonstrate on-chip molecular fingerprinting by measuring the refractive index dispersion of gas in the mid-IR using a thermally tuned suspended silicon microring resonator. We show CO2 sensing down to 1000 ppm at 4.23 µm wavelength.
