| 摘要 |
A photonic device/a method of forming a photonic device comprising a length of optical fibre [11] loaded in tension over a portion of its length, an in-fib re Bragg grating [14] formed within the tensile loaded portion of the length of fibre, two longitudinally spaced apart supports for the fibre [10], longitudinally aligned channels [19] in the supports, for receiving the fibr e, a carrier [12] in which the supports are located, and glass solder [21] contained within the channel anchors the embedded fibre to the support, the supports being formed from a material that has a coefficient of thermal expansion greater than that of the glass solder.
