Paper Abstract

A temperature fiber sensor based on CdSe-nanocrystallite- doped phosphate glass as a sensing element is reported. This glass is shown to exhibit a reversible temperature-induced absorption edge shift at temperatures less than the annealing temperature of the glass (<370°C). A dual-wavelength detection scheme based on a reflective grating and bi-cell photodiode is employed to eliminate the effects of variable signal losses in the intensity-dependent sensor. A sensor prototype, tested in the temperature range of -20 to +120°C, is shown to exhibit a linear response to temperature variations.
