Abstract
Asymmetric stress in the tip of a polarization-maintaining optical fiber is measured using the photoelastic effect to determine the fiber polarization axes of two fibers appointed to be joined. The fibers are rotated to align their respective polarization axes and are joined together. A single polarization-maintaining optical fiber is thereby produced in an accurate, reliable, time efficient and cost effective manner.
