Low-concentration detection of CO₂ using suspended silicon waveguides in the mid-IR 2022 (English)In: 2022 Conference on Lasers and Electro-Optics, CLEO 2022: Proceedings, Institute of Electrical and Electronics Engineers Inc. , 2022Conference paper, Published paper (Refereed)

Abstract [en]

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.
