ABSTRACT:
An electrooptical waveguide assembly comprising a plurality of waveguide blocks wherein each of said waveguide blocks has a waveguiding region and a substrate region supporting the waveguiding region, the waveguide blocks being connected in a row to have successive face-to-face contact in such a way that said waveguiding regions are aligned for continuous optical-beam transfer from one of said waveguide blocks to the next, and the crystallographic orientations of any two neighboring waveguide blocks are different from each other so that two orthogonal propagating modes being guided through said waveguiding regions experience a balanced electrooptic effect from electric fields applied to the waveguide.
