Claim Text:
1. A method of forming a semiconductor structure comprising: forming a first trench within a semiconductor-on-insulator (SOI) substrate, the first trench extending through a top semiconductor layer of the SOI substrate and a buried insulator layer of the SOI substrate and into a handle substrate of the SOI substrate; forming a dielectric waveguide material stack in the first trench; forming at least one electronic device in the top semiconductor layer, wherein the at least one electronic device comprises at least one bipolar junction transistor (BJT); forming a second trench extending through a portion of the dielectric waveguide material stack, the second trench re-exposing a portion of the bottom surface of the first trench; epitaxially depositing a compound semiconductor seed layer on the exposed portion of the bottom surface of the first trench; epitaxially depositing a compound semiconductor buffer layer on the compound semiconductor seed layer; and forming an optoelectronic device on the compound semiconductor buffer layer within the second trench.
