Claim Text:
1. A method of forming an optoelectronic device and a device on a single chip comprising: forming a semiconductor-on-insulator (SOI) substrate in a first region and a second region, the SOI substrate includes a semiconductor layer on a first insulator layer, and the first insulator layer is on a substrate; removing the semiconductor layer and the insulator layer from the second region, wherein a top surface of the substrate is exposed; forming a second insulator layer on the semiconductor layer in the first region; forming a substrate extension layer on the exposed substrate in the second region; forming the device on the substrate extension layer; forming a device insulator layer covering the device in the second region; forming a waveguide in the second insulator layer; and forming the optoelectronic device in the first region, the optoelectronic device has a bottom cladding layer, an active region, and a top cladding layer, wherein the bottom cladding layer is on the semiconductor layer, the active region is on the bottom cladding layer, and the top cladding layer is on the active region.
