Abstract
A fiber-optic thermometer probe has an optical fiber with a sensing portion, namely a region of reduced cladding thickness coated with a temperature-dependent refractive index material to provide variations in propagated light power upon changes in temperature in a vicinity of the sensing portion. A reflective interface optically coupled to a core of the optical fiber reflects light propagated therein. The sensing portion can be the tip and prepared by etching using a dipping process.
