A pathway towards the development of heterogeneously integrated devices
FFLOWS is an European R&D developer of ferroelectric films for integration in photonics and is currently focusing on barium titanate (BaTiO3) thin films. The availability of high-quality BaTiO3 films enables the development of heterogeneously integrated electro-optic modulators, a key component for future low-power photonic applications in the medium and high frequency range, including sensors, optical interconnects and neuromorphic computing. Here, FFLOWS is driving the development and introduction of heterogeneously integrated devices into existing photonic process flows.
The FFLOWS technology
We have developed a solution-based process for the fabrication of highly oriented BaTiO3 films on various substrates (Si, SiO2, glass, ITO, ...) or directly on planarized photonic integrated circuits (PICs) currently up to a wafer size of 100 mm.

The key aspects of our BaTiO3 film
The BaTiO3 film developed by us has a fiber texture with its elongated c-axis is oriented in-plane (a-axis orientation). This unique film texture enables the integration of waveguides and electrodes without any orientation restrictions while maintaining high modulation efficiency and bandwidth.
