Research output: Patent


A method of temperature stabilising optical waveguides having positive thermal optical path length expansion, in particular fiber Bragg gratings or optical fiber DFB lasers or optical fiber DBR lasers, comprising affixing the optical waveguide to at least two points of a negative expanding fixture; said negative expanding fixture comprising one or two V-shaped displacement amplifiers made from a material with a higher positive CTE mounted in a frame made of a material with lower positive CTE; the V-shaped displacement amplifier is mounted on a support in such a manner that its motion in directions substantially perpendicular to the axis of the mounted fiber device is restrained by the support and transferred to (amplified) displacement along the fiber axis.
