Abstract
The spatial variation of the phase difference Φ(z) between collinear guided waves is measured interferometrically by scanning a localised perturbation along the guide. Milliradian phase resolution is achieved by the use of a quadrature signal. The method is demonstrated with TE⇔TM coupling in Ti:LiNbO3. It yields the absolute value and the uniformity of the birefringence Δβ(z)=dΦ/dz
