Abstract
An optical device includes a semiconductor substrate having a major surface, and an optical waveguide structure on the major surface. The optical waveguide structure comprises a lower optical core, an upper optical core, and an intermediate optical cladding, where the upper optical core is vertically above the lower optical core and the intermediate optical cladding separates and is in contact with the optical cores. The optical cores are optically coupled in first and second sections of the optical waveguide structure near the respective first and second ends, and the optical waveguide structure has a parallel pair of optical waveguides extending from the first section to the second section with each of the optical waveguides including one of the optical cores.
