Abstract
A method of making and an element having a light waveguide in which the input-output area through which light is input or output is made into a light waveguide of a high threshold value of optical damage formed by outside diffusion of lithium oxide or by ion exchange and the optically functional portion in which the waveguide light is modulated or deflected by extraneous action is made into a light waveguide formed by diffusion of a metal of high light modulation or light deflection efficiency.
