Abstract
A method of integrating an optoelectronic device comprising a Pockels material, such as lithium niobate (LiNbO3), includes forming an optoelectronic device layer over a semiconductor layer. The optoelectronic device layer includes a patterned optoelectronic device segment in an interlayer dielectric. A window is etched in the interlayer dielectric using the patterned optoelectronic device segment as a sacrificial etch stop. The patterned optoelectronic device segment is removed in the window. The optoelectronic device comprising the Pockels material is formed in place of the removed patterned optoelectronic device segment. The optoelectronic device comprising the Pockels material may be formed from an optoelectronic chiplet.
