A photonic device/a method of forming a photonic device comprising a length of
optical fiber loaded in tension over a portion of its length, an in-fiber Bragg
grating formed within the tensile loaded portion of the length of fiber, two longitudinally
spaced apart supports for the fiber, longitudinally aligned channels in the supports,
for receiving the fiber, a carrier in which the supports are located, and glass
solder contained within the channel anchors the embedded fiber to the support,
the supports being formed from a material that has a coefficient of thermal expansion
greater than that of the glass solder.
