In the last decade, research in my group was focused on the development of ferroelectric thin films for integration in nanophotonic devices.  The deposition of lead zirconate titanate (PZT) and barium titanate (BTO) thin films has been optimized greatly. With these materials high-speed electro-optic modulators have been demonstrated. In the next few years, the research will focus on two aspects. The first track will focus on a completely new class of thin films that may exhibit electro-optic coefficients which are a factor 2 higher. With initial verification of their electrical and optical properties, the aim is to demonstrate next generation modulators using these new materials. The second track will focus on bringing the building blocks based on the proven materials (PZT and BTO) to a wider span of photonic circuits targeting tunable and trainable neuromorphic photonic circuits and nonlinear integrated light sources.
