Abstract
It is found that the temperature sensitivity of a fiber polarimeter can be significantly reduced by UV irradiation of the fiber. A stress-relief model is proposed to explain the mechanism, which is proposed to be a consequence of the breakage of oxygen-deficient bonds (wrong bonds) in the glass network through single-photon or multiphoton absorption, with a subsequent relaxation of the tensile stresses in the fiber core.
