Guided light propagation in two-layer LiF/NaF structures grown on glass sub
strates is reported for the first time. LiF/NaF based waveguides have been
grown at different temperatures. The films texture analysis revealed both t
he influence of the underlying NaF buffer layer on the structure of the gui
ding LiF film and the importance of the film microstructure on the light pr
opagation properties. (C) 2000 Elsevier Science S.A. All rights reserved.
