Paper Abstract

A kind of relative humidity sensors is presented. The sensors consist of a layer of three dimensional periodic films and an optical fiber bundle. The three dimensional periodic films which are polystyrene opal films, silica inverse opal films and composite photonic crystal films were self-assembled on end facet of the optical fiber bundle end facet. Principle of the sensor is that optical reflection peak of the three dimensional periodic films is sensitive to relative humidity, and optical reflection spectra of the films can be measured from the other end of the fiber bundle.
