Abstract A new method of optical gas sensing is presented which uses evanescent waves of optical fibers. Gas detection can be done in a simple, flexible, and possibly distributed way using a single optical fiber as both the sensor with an active element of 10 cm and the transmission line for optical signals. The detection of several single gaseous species — such as hexane, trichloro-trifluoro-ethane, methane, acetone, etc. — as well as gaseous mixtures in a concentration range of 1–10% could be achieved with an average reproducibility of 2–3% with a chalcogenide fiber optic coupled to an IFS 88 Bruker spectrometer.
