Abstract

A three-section fiber model has been used to derive the formula for measuring the birefringence of single-mode optical fibers. This analysis relieves the problems associated with measurements of the birefringence of optical fibers with very short beat length. The distortion of the measured curves for fibers with nonuniform birefringence is discussed. A newly developed nulling scheme makes the measurement accurate and stable.
