Stress analysis of optical fibers by a finite element method

Stress-induced birefringence in single-mode optical fibers having arbitrary shape of core has been investigated using a finite element method. The calculated modal birefringence due to the thermal stress and/or stress caused by external forces in noncircular core fibers is compared with the values obtained by measurement of polarization properties, showing good agreement.
