Abstract:
1. A method for manufacturing an apparatus, comprising: providing a substrate having laterally adjacent first and second lateral regions on a planar surface thereof; forming an optical core layer on the substrate in the first and second lateral regions; forming an absorber or gain medium layer over the optical core layer in the second lateral region; forming an upper optical cladding layer on the optical core layer in the first lateral region; forming a doped semiconductor layer over the upper optical cladding layer in the first lateral region and over the absorber or gain medium layer in the second lateral region; and wherein the first lateral region forms a passive optical waveguide structure and the second lateral region forms a photodiode or amplifier structure, the photodiode or amplifier structure being optically connected to receive light from the passive optical waveguide structure.
