Experimental study on the origin of optical waveguide losses by means of Rayleigh backscattering measurement.
Scattering is often considered as the main cause of the huge attenuation difference between optical fibers and integrated optical waveguides. In order to evaluate the magnitude of scattering in those waveguides, an optical low coherence reflectometry experiment has been conducted, showing that the amount of backscattered light is not enough to explain that difference in losses.
