Abstract
An optical waveguide sensor using an intermediate layer between the preformed optical core and the optical cladding material. This intermediate layer comprises a material that is doped with a sensor material to respond to an analyte of interest by luminescing or by developing optical absorption in the transmission region of the core fiber and that has a refractive index greater than the preformed core. Two configurations provide sensors for ionizing radiation capable of measuring the dose rate and the integrated deposited dose.
