The invention provides a package which varies the tension within a fiber Bragg grating (or other fiber-based optical device) by resilient deflection of a fiber support member through differential thermal expansion, thereby allowing the temperature/tension characteristics of the package to be tailored so as to provide the desired optical characteristics throughout a wide temperature range. The fiber tension/temperature correlation may be tailored using the linear coefficient of expansion of two different materials, by varying the resilient flexibility of a beam supporting the fiber, by varying a length of an arm extending from the beam to the fiber, by varying the resilient strength of the arm, and the like. By relying on the resilient deformation of a flexible fiber support structure, the present invention provides a large number of degrees of freedom within the package design parameters. Where such precise control over the temperature/tension correlation is not required, the invention provides alternative compensation packages which can be mass-produced easily.
