Abstract

In this work we present nondestructive measurements of the optical parameters and propagation losses of multimode planar H_xLi_1-xNbO₃ waveguides using m-line spectroscopy. The dependence of the attenuation coefficient on the effective refractive index was investigated for z- and y-cut samples. Theoretical modeling of the experimental data revealed that the main loss mechanism in z-cut waveguides is the surface scattering, while in y-cuts the mode conversion dominates.
