Longitudinal Strain Induced Birefringence in Highly Birefringent Fiber for Dynamic Compensation of Polarization Mode Dispersion

The paper addresses a compensation method of polarization mode dispersion based on longitudinal strain applied to a highly birefringent fiber introduced as apart from optical fiber link. As an introduction a short overview of the polarization mode dispersion compensation methods known up-to-now is done. Dependence of polarization mode dispersion on longitudinal strain is discussed. Some results of experiment with birefringence changes due to longitudinal strain in the bow-tie highly birefringent fiber necessary for dynamic polarization mode dispersion are presented.
