Abstract

Polarisation mode dispersion measurements based on optical heterodyne detection are demonstrated. Using the detection technique, length dependence of group delay difference between two orthogonally polarised HE₁₁ modes in an elliptical-core fibre was measured at a wavelength of 1.3 μm. The modal dispersion was found to depend linearly on length in the range of 0–500 m for a fibre with modal birefringence of 1.5×10⁻⁵.
