Absorption loss and Kerr nonlinearity in barium titanate waveguides by Annina Riedhauser, Charles Möhl, Johannes Schading, Daniele Caimi, David I. Indolese, Thomas M. Karg, Paul Seidler

“…Material absorption sets a lower limit to optical loss and is thus a crucial property to determine, particularly for integrated photonic devices. Using cavity-enhanced photothermal spectroscopy, we measure the absorption loss of BaTiO3 ridge waveguides at wavelengths near 1550 nm to be αabs = 10.9−0.4+5.8 dB m−1, well below the propagation losses due to other sources, such as scattering. …”
