Abstract: The techniques of preparing PMMA/DR1 periodic waveguide on polymer film by photobleaching method have been studied in this paper. The grating coupler was realized in our experiment. The effective refractive index change was determined by measuring the direction change of the outcoupled beam during photobleaching.
