Abstract

A method of fabricating a photonic device includes: forming a photonic device structure that includes a SOI substrate, which includes a bulk substrate layer, a buried oxide layer on the bulk substrate layer and an active semiconductor layer on the buried oxide layer; forming an electrically conducting layer in electrical contact of the buried oxide layer, and forming a BEOL structure on a surface of the active silicon layer.
