This contribution summarizes on recent findings of planar Bragg grating sensors, functionalized with cyclodextrins, for the detection of ozone depleting trichlorofluoromethane. Detection limits as low as 5 ppm are feasible whereas sensitivity and dynamic depend on the employed cyclodextrin class. The prospect of transferring the technology from silicas to polymer-based devices is also presented.
