Abstract
Provided is an apparatus and method for manufacture thereof. The apparatus includes a passive optical waveguide structure and a photodiode detector structure. The structures are located on a substrate, and the photodiode detector is laterally proximate to the semiconductor passive waveguide structure. The passive optical waveguide structure includes a first lateral portion of a semiconductor optical core layer on the substrate, a semiconductor upper optical cladding layer on the optical core layer, and a first lateral portion of a doped semiconductor layer on the upper optical cladding layer. The photodiode detector structure includes a second lateral portion of the semiconductor optical core layer, a semiconductor optical absorber layer on the optical core layer, and a second lateral portion of the doped semiconductor layer.
