| 摘要 |
A package for temperature compensating a Bragg grating region (28) of an optical waveguide fiber (26). The package includes a first tubular member (12) having a low coefficient of thermal expansion attached to the optical fiber (26). A second tubular member (18), having a coefficient of thermal expansion greater than that of the first tubular member (12), is attached to the first tubular member (12). A third tubular member (24), having the same coefficient of thermal expansion as the first tubular member (12) has one end (32) attached to the optical waveguide fiber (26) and the other end (32) attached to the second tubular member (18). The three tubular members (12, 18, 24) are coaxial with one another and the Bragg grating region (28) is encapsulated by the package.
