ABSTRACT:
A temperature probe includes a sensor material optically communicating with a waveguide, and a sheath having a sheath coefficient of thermal expansion substantially matched to a thermal expansion coefficient of the waveguide. The waveguide has first and second ends secured proximate corresponding sheath ends. In another aspect of the invention, waveguide ends are secured near the sheath ends, the sheath is bent at one or more locations so that it is noncylindrical, and a midsection of the waveguide is loosely held within the bent sheath. In still another aspect of the invention, a metallic tube with the sensor material disposed therein is secured to the waveguide by direct attachment to a metallic coating on the waveguide.
