The propagation loss of Si0.9 Ge0.1/Si planar optical waveguides has been measured at wavelengths of 1.15 and 1.523µm. The results show that these waveguides have a low propagation loss (<ldB/cm) at a wavelength of 1.523µm, which is due to the intrinsic absorption of SiGe whereas at a wavelength of 1.15µm its loss is determined by both the SiGe absorption edge and defects at the SiGe/Si interface.
