Abstract: The present invention relates to an optical-fiber device comprising at least one component (11) integrated into the fiber (10), and a support assembly on which the fiber (10) is fixed at two points (1322, 1332) situated respectively on either side of the integrated component (11), which support comprises at least two elements (120, 130, 132) possessing different thermal-expansion coefficients which are arranged functionally in series between the two points of fixing of the fiber, characterized in that the interface (131, 133) between the two elements (120, 130, 132) possessing different thermal-expansion coefficients is at least substantially perpendicular to the axis of the fiber (10), and in that the means for support of the optical fiber (10) comprise a support assembly consisting of three pieces (130, 120 and 132) arranged in series, in a Z-shaped geometry.

Abstract: The invention concerns an optical device comprising an optical fiber including at least an integrated component, a support including two fixing zones wherein the optical fiber is fixed respectively at the two zones located on either side of the component. The invention is characterized in that the support comprises, between the two fixing zones, at least a linking beam capable of bending and the device further comprises means for imposing a controlled bending to the beam, adapted to adjust the distance between the two fixing zones.
