ABSTRACT:
An optical waveguide (20) is comprised of a core layer (20) fabricated on an interference layer (18). The interference layer (18) is supported by a lower cladding layer (16) deposited on a semiconductor substrate (12), a and Light travels through the core layer and is coupled into the interference layer by a grating. An electronic element in the interference layer modulates the light passing through the interference layer. The modulated light is then coupled back into the core layer by either another portion of the grating, or a separate grating.
