Determination of the attenuation of planar waveguides by means of detecting scattered light
Institute of Physics, Silesian University of Technology, 44-100 Gliwice, Poland
Due to the variety of waveguides in planar structures, the measurements of attenuation are characterized by a considerable variety of applied methods, developed for given type of waveguides. The method of measuring scattered light is, therefore, of much importance in the case of waveguides with a rather high attenuation, because it is an exceptionally fast and simple method, which is doubtlessly the effect of the development of numerical detection systems. The paper presents the process of measurements basing on scattered light, combined with an analysis of its application, as well exemplary results concerning the planar structures of waveguides achieved by means of ion exchange on soda-lime glass.
