Abstract
An optical fiber may be constructed of a material having at least first and second constituents. The constituents and their relative abundance are selected such that the aggregate Brillouin frequency-shift response exhibited by a fiber constructed using the combined material is insensitive to a selected physical condition, such as temperature or strain, or the sensitivity is below an acceptable application-specific level, over an acceptable range of conditions. The constituents are selected such that the slopes or derivatives of the Brillouin frequency-shift response (with respect to the selected physical condition) of two of the constituents have opposite signs, and are combined in proper quantities such that the constituents balance each other to reduce the slope or derivative of the aggregate Brillouin frequency-shift response of the combined material to zero, or to an acceptable application-specific level, over an acceptable range of conditions.
