Abstract

Two different optical fiber-based sensor approaches are compared for the detection of hydrogen gas. The two sensors both use Fabry-Perot techniques that have been investigated for some time for other applications. One involves the use of an Extrinsic Fabry-Perot Interferometric (EFPI) sensor scheme, and the other uses a nanoFabry-Perot (nanoFP) cavity that is formed on the distal end of a fiber endface. It is found in general that the sensitivity of the EFPI sensor is higher than that of the nanoFP, but that its speed of response is slower.
