"To scale the bandwidth even higher e.g. towards 200Gbaud operation, compound semiconductors such as indium phosphide can be integrated onto silicon photonic or silicon nitride wafers. Another alternative is barium titanate (BTO). This is a very promising electro-optic material that can push the performance of modulators even further. Imec is looking at integrating BTO-based modulators into its 200mm platform. An important focus is to adapt the BTO deposition techniques to volume scaling. Unlike other material systems such as LiNbO3, BTO can be brought into CMOS foundries, a critical advantage for manufacturing at scale."

I was thinking that POET can bring LiNbO3 into CMOS foundries or am I wrong?
