Abstract

The invention is a temperature compensating structure for a fiber Bragg grating (FBG) contained in optical fiber (11). The structure comprises two plates (12, 13) made of material having different temperature coefficients of expansion and bonded together. The optical fiber (11) is bonded to the exposed surface of the plate (12) having the lower temperature coefficient. The structure bends with changes in temperature and produces an elongation of the fiber (11) with decreasing temperature.
