Abstract
An optical fiber () utilized as a sensor for measuring a parameter of interestsuch as temperature, strain, photonic energy intensity, electric field intensity and magnetic field intensity is provided. A first optical cladding layer () is disposed on an optically transmissive core () that includes one or more optical gratings (-). The optical grating(s) (-) modifies a propagation path of selected wavelengths of light propagating through the core (). The optical grating(s) (-) also varies the index of refraction of the first optical cladding layer (). The selected wavelengths of light are determined in part by the index of refraction of the core materialas dependent upon a parameter of interestapplied to the core materialand as varied by the optical grating(s) (-). One or more detectors () are used for determining the properties of the reflected and/or transmitted light. Knowing the properties of the reflected and/or transmitted light, a parameter of interestcan be determined.
