Abstract: An optical waveguide device is proposed which comprises a substrate, thereupon a lower cladding layer, thereupon an upper cladding layer and between said cladding layers a waveguide element. The influence of the substrate on the stress-induced birefringence of the optical waveguide device is reduced by modification of the substrate from underneath the waveguide element.
