| 摘要 |
An athermal optical device and a method for producing the device, such as an athermal optical fiber reflective grating (20), are described. The athermal optical fiber reflective grating device (20) comprises a negative expansion substrate (22), an optical fiber (24) mounted on the substrate (22) surface, and a grating (26) defined in the optical fiber (24). The method for producing the athermal optical fiber reflective grating (20) device comprises providing a negative expansion substrate (22), mounting an optical fiber (24) with at least one reflective grating (26) defined therein onto the substrate (20) upper surface, and affixing the optical fiber (24) to the substrate (22) at at least two spaced-apart locations (30, 32).
