Abstract
This paper deals with an experimental nondestructive technique for the measurement of modal
birefringence of integrated optical waveguides. The method is based on a magneto-optical perturbation technique
combined with a highly sensitive polarimeter. Magneto-optical modal conversion, through the Verdet constant of the
waveguides, and its dependence on the perturbation length are discussed. In this paper, the practical application of
this equipment is proposed for the measurement of modal birefringence in totally or partially buried ion exchanged
waveguides.
