Abstract
The present invention relates to a temperature-compensated optical waveguide device. The temperature-compensated optical waveguide device includes a substrate having a first end and a second end. A first mount is coupled to the first end of the substrate. The first mount includes a first surface, the first surface having a first grove and a first recess intersected by the first groove. A second mount is coupled to the second end of the substrate. The second mount includes a second surface having a second grove and a second recess intersected by the second groove. The first groove and the second groove are substantially aligned with one another; and an optical waveguide fiber coupled to the first mount and the second mount. The optical waveguide fiber has a Bragg grating. The substrate has a first coefficient of thermal expansion, the first mount has a second coefficient of thermal expansion and the second mount has a third coefficient of thermal expansion. The second and third coefficients of thermal expansion are greater than the first coefficient of thermal expansion.
