| Zusammenfassung: | A method for preparing planar light waveguide device includes providing a base plate, coating clad material on base plate to form a cladding layer, curing said layer and coating core material on said layer to form a core layer, forming cover layer on core layer and using polarized light to shine cover layer at least once for having the opening of core layer corresponding to cover layer exposed once or a number of times for forming light path, removing off cover layer and curing the rest of core layer and the light path. |
