Patent ID: 6839487

Claim:
Optical-fiber device comprising at least one component ( 11 ) intergrated 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 intergrated component ( 11 ), which support assembly 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 the fiber, wherein an interface ( 131 , 133 ) between at least two elements ( 120 , 130 , 132 ) possessing different thermal-expansion coefficients is at least substantially perpendicular to the axis of the fiber ( 10 ), and the support assembly includes three pieces ( 130 , 120 and 132 ) arranged in series, in a Z-shaped geometry said device further comprising: means for adjusting the distance separating two points ( 1322 , 1332 ) for anchoring the fiber ( 10 ) onto the support assembly ( 120 , 130 ) by deformation of said support assembly, wherein the adjusting means comprise a screw transverse to the axis of the fiber ( 10 ).
