Paper Abstract

The study of guided waves in a thin layer allows a precise characterization of refractive index and thickness. In our experimental equipment the propagation constants of guided modes were measured by the dark mode spectroscopy technique. Series of dark lines known as the m-lines were observed on the screen. Angles synchronous to the propagating modes were calculated from measurement of the angular distribution of the m-lines. The positions of the m-lines depends on thin film absorption and coupling strength.
