Lithium niobate(LiNbO_(3),LN)channel and ridge waveguides have been successfully fabricated by He ion implantation,which has energy of 500 keV and fluence of 1.5×10^(16)ions/cm^(2) and is combined with lithography and the precise diamond dicing *** refractive index profile of the annealed LN planar waveguide was *** propagation loss of the channel waveguide with a width of 10μm and that of the ridge waveguides with widths of 25μm and 15μm were investigated by the end-face coupling *** our work,the factors that affect the waveguide properties of channel and ridge waveguides were revealed.
