ABSTRACT:
A method of coupling electro-optical components (20) to integrated-optical waveguides (12) which are provided in a substrate (10) comprises the steps of: (a) applying an etching agent to the substrate (10) such that a cavity (18) is etched into the surface of the substrate (10) and intersects the waveguide (12); (b) positioning and holding an electro-optical component (20) within the cavity (18) in the desired position relative to the waveguide (12); and (c) encasing the component (20) within the cavity (18) into a rigidifying cast material having a refractive index matched to the refractive index of the waveguide (12). Other embodiments provide for making the cavity by boring or milling.
