Abstract
A low-loss and polarisation-insensitive singlemode BaTiO3 thin-film waveguide is reported. Polarisation-dependent loss as low as 0.1 dB/cm at a wavelength of 1.55 μm has been achieved by a novel Si3N4 strip-loaded BaTiO3 waveguide structure. Propagation loss of less than 0.9 dB/cm for both TE and TM polarisations was measured
