ABSTRACT:
An integrated-optical device including a substrate having waveguide and a plurality of electrodes to receive electrical signals for controlling the light transmission through the pathways. The waveguide pathways are in an interaction zone of an electro-optically active waveguide material whose refractive index changes in response to electrical signals applied to the electrodes, and also in an access zone providing optical access to the interaction zone. The active waveguide material in the interaction zone is preferably a different material from the waveguide material in the access zone, enabling improved performance and/or simpler fabrication in a number of described respects.
