Ferroelectric FiLm Integration for Electro-Optics - FFLIES

FFLIES aims to fabricate a heterogeneously integrated BaTiO3 film optical phase modulator by μ-transfer printing BaTiO₃ coupons on photonic integrated circuits (PICs). The performance of the modulator will be validated by determining the Figure of Merit (FoM) (VπLα) and compared with the current state-of-the-art in heterogeneously integrated phase modulators (VπLα < 5 V dB). Demonstration of a proof of performance of the fabricated BaTiO₃ films and showing compatibility with a Back-End-of-Line (BEOL) integration method (e.g. μ-transfer printing) are vital aspects in the valorization pathway. The overall goal is to establish a spin-off company to commercialize BaTiO₃ wafers for use in silicon photonic applications at the end of this project.
