Paper Abstract

A fiber-optic interferometer to measure differences in temperature between two single-mode fiber arms is described. Temperature changes are observed as a motion of an optical interference fringe pattern. Values are calculated for the temperature dependence of the fringe motion. Temperature measurements are made with the interferometer, and the experimental results for sensitivity are in good agreement with the theoretical values.
