Abstract
The relationship between waveguide properties and their morphological regularity is investigated for the LB films prepared by two preparation methods. The optical propagation loss of the LB film prepared by the multi-step creep method was 2.5 dB(DOT)cm-1, whereas that of the LB film prepared by the continuous compression method was 8.4 dB (DOT)cm-1. The lower propagation loss of the LB film prepared by the multi-step creep method results from a remarkable reduction of the surface light scattering due to the flat surface morphology of the LB film.
