An optical filter (1) having at least one optical fiber component (2) and a thermal compensation device (3) which includes a first, second and third member (4), (5), (6) in which the thermal compensation device has a first and a second fixing point (7), (8), the first, second and third members are made from materials having first, second and third thermal expansion coefficients, the optical fiber component is attached to the thermal compensation device at the first and the second fixing points thus defining a composite thermal expansion. The optical filter is such that the composite thermal expansion compensates for thermal behavior of the optical fiber component.
L'invention concerne une fibre optique (1) comprenant au moins un élément de fibre optique (2) et un dispositif de compensation thermique (3) comprenant un premier, un deuxième et un troisième éléments (4), (5), (6) présentant un premier et un second points de fixation (7), (8) destinés au dispositif de dilatation thermique. Les premier, deuxième et troisième éléments sont fabriqués à partir de matériaux présentant des premier, deuxième et troisième coefficients de dilatation. L'élément de fibre optique est relié au dispositif de compensation thermique par les premier et second points de fixation, définissant ainsi une dilatation thermique composite. La fibre optique est telle que la dilatation thermique composite compense le comportement thermique de l'élément de fibre optique.
