Abstract
A process for fabricating an optoelectronic device having a germanium-on-silicon photodiode coupled to an SiNwaveguide includes producing a semiconductor substrate having a semiconductor stack of thin layers configured to form segments of a semiconductor structure of the photodiode, producing a photonic substrate having the SiNwaveguide, and transferring and bonding the semiconductor substrate to the photonic substrate. The photodiode is produced by photolithography and etching of the semiconductor stack to form the semiconductor structure which is then located above the waveguide.
