CA 2225342

A method for side writing Bragg gratings, having minimal birefringence, in a waveguide structure is disclosed. The method employs the orientation of the polarization direction of the writing light beam relative to the long axis of the waveguide structure together with the orientation of the intrinsic birefringence slow axis to effectively minimize birefringence in the subject grating.

Méthode d'enregistrement latéral de réseaux de Bragg à biréfringence minimale dans une structure de guide d'onde. La méthode utilise l'orientation de la direction de polarisation du faisceau de lumière d'enregistrement par rapport à l'axe longitudinal de la structure de guide d'onde conjointement avec l'orientation de l'axe lent de biréfringence intrinsèque afin de réduire efficacement au minimum la biréfringence dans le réseau visé.
