Optical attenuators for proton-exchanged and annealed waveguides in LiNbO3 are modeled by the matrix effective refractive index (MERI) method. It is shown theoretically and experimentally that an attenuation of 1.6 dB/mm can be expected for a titanium-gold metallic overlay. The theory indicates that this attenuation can be increased to nearly 4.5 dB/mm by placing a titanium dioxide layer between the waveguide surface and the metallization.
