Abstract

We present a hybrid barium titanate photonics platform exhibiting exceptionally low losses of 0.7 dB/cm and realize ring resonators with intrinsic quality factors exceeding 6×105. Measurement of Vπ L = 0.56 V·cm in electro-optic modulation experiments demonstrates the platform’s potential.
