"Electro-optical Modulation of Ferroelectric Barium Titanate Waveguides"

Abstract: With the advent of silicon photonics and nano-modulators, a new paradigm for computation is taking shape. However, Si device modulators suffer from high power consumption and large footprints and so novel materials are needed to realize this technology. In its ferroelectric phase, Barium Titanate (BTO) has a large Pockels coefficient due to its polarized domains and is a good candidate material for electrooptical modulation devices. Thus, device footprints and power consumption can be greatly reduced. In this talk, I will share how we design, fabricate, and test the electrooptic modulation devices in thin film BTO.
