Abstract:
A temperature compensating optical waveguide device comprising:a substrate, said substrate having: a first end; and a second end; a first mount coupled to said first end, said first mount including: a first surface, said first surface having a first groove; and a first recess intersected by said first groove; a second mount coupled to said second end, said second mount including: a second surface, said second surface having a second groove; and a second recess intersected by said second groove; wherein, said first groove and said second groove are substantially aligned with one another; and an optical waveguide fiber coupled to said first mount and said second mount; wherein said optical waveguide fiber has a Bragg grating; wherein said substrate has a first coefficient of thermal expansion; wherein said first mount has a second coefficient of thermal expansion; wherein said second mount has a third coefficient of thermal expansion; wherein said second coefficient of thermal expansion is greater than said first coefficient of thermal expansion; wherein said third coefficient of thermal expansion is greater than said first coefficient of thermal expansion.
