Abstract :
Summary form only given. We report on accurate measurements of layer thicknesses, modal effective indices and guided-wave losses. The thickness in the multilayer have been measured through Kiessig fringe analysis in X-ray reflectometry. This lead to an accurate estimation of AlGaAs percentage in MBE grown GaAs-AlGaAs superlattices.
