“…The coated LPG was spliced into this cavity and light was introduced using a 95:5 fiber-fiber coupler (see Figure 8 ). A similar setup has been previously used by Bo et al for temperature and strain measurements [ 53 ]. Xylene and cyclohexane were introduced at different saturation pressures between 2.5% and 50% and their concentrations were measured through the change in phase angle at 1550 nm.…”

Waveguide-based cavity ring-down spectroscopy (CRD) can be used for quantitative measurements of chemical concentrations in small amounts of liquid, in gases or in films. The change in ring-down time can be correlated to analyte concentration when using fiber optic sensing elements that change their attenuation in dependence of either sample absorption or refractive index. Two types of fiber cavities, i.e., fiber loops and fiber strands containing reflective elements, are distinguished. Both types of cavities were coupled to a variety of chemical sensor elements, which are discussed and compared.

a b s t r a c tAn etched long-period grating was used as a refractive index sensor for vapours of four volatile organic compounds, i.e. m-xylene, cyclohexane, trichloroethylene and commercial gasoline. The sensitivity to the vapours was further increased by solid-phase microextraction into a coating made of polydimethylsiloxane (PDMS)/polymethyl-octylsiloxane (PMOS) co-polymer. By further amplification of the optical loss in an optical cavity made of two identical fiber-Bragg gratings and interrogation by phase-shift cavity ring-down spectroscopy we could detect and distinguish xylene (detection limit: 134 ppm) from trichloroethylene (3300 ppm), cyclohexane (1850 ppm) and gasoline (10,500 ppm).
