Abstract
Three stress effects on the state of polarization in high birefringent polarization-maintaining fibers are reviewed. The stresses induced in PM fibers by the different thermal expansion coefficients between the stress-applying parts and the surrounding glass make stress-induced-birefringent fibers very sensitive to temperature variations. Mechanical perturbations can change the polarization state of PM fibers. Temperature changes can enhance any random microbends in wound optical fiber and cause mode coupling. The effect of periodic bends, small-radius bends, and twist and fiber individual crossing in the presence of transverse pressures on the degradation of the state of polarization rotation is investigated. A procedure for evaluating the performance of wound PM fibers in low temperature environments is also discussed.
