Abstract:
A temperature-adjusting optical fiber package comprising:a first member having a first end and a second end and defining an axis therebetween, the first member having a first thermal coefficient of expansion;a second member having a second thermal coefficient of expansion which is different than the first coefficient, the second member affixed axially along the first member to impose a resilient lateral deflection in the first member which varies with temperature; andan optical fiber portion with a first end and a second end, the fiber between the first and second portion ends having an optical characteristic which varies with tension, wherein the fiber is substantially axially oriented; andat least one arm extending laterally from the first member to the optical fiber so as to amplify changes in the tension of the optical fiber from changes in the deflection, the at least one arm including a first arm extending from adjacent the first end of first member to the first portion end, the second fiber end coupled to the first member adjacent the second end of the first member so that the fiber between the first and second portion ends defines an unsupported span, wherein the affixed first and second members impose a tension in the unsupported span of the fiber which varies with the resilient deflection of the first and second members.
