    Optical waveguides with a high refractive index contrast were fabricated on silicon-on-insulator (SOI) and polysilicon. The attenuation of 2dB/cm was achieved for SOI, and 11 dB/cm for hydrogenated polysilicon waveguides. Unlike in SOI waveguides, where the main contribution to attenuation is due to the surface scattering, a significant part of attenuation in polysilicon originates from absorption and scattering in the material.
