Abstract

In this Letter a new method is proposed for measuring the beat length of linearly birefringent optical fibers. In this method the beat length is determined from the wavelength dependence of the phase difference between two orthogonally polarized HE11 modes at the output end of a sample fiber. The important feature of this method is the wide range of the measurable beat length (0.4 mm–1 m). The principle, the experimental setup, and the result of the experiment are described.
