Abstract
In an electro-optical modulator, an electro-optical modulation layer is bonded to a cladding layer that overlies a substrate. A modulation zone waveguide is optically coupled to the electro-optical modulation layer and optically coupled to an I/O waveguiding structure embedded in the cladding layer. The I/O waveguiding structure is conformed to guide input light toward the modulation zone waveguide and to guide output light away from the modulation zone waveguide.
