A method for fabricating a nonlinear optical waveguide with gradient refractive index distribution, in which a nonlinear optical crystal is prepared; a type of first heavy ions, a type of second heavy ions and parameters related to an irradiation process are determined; the first heavy ions are accelerated to generate a first ion beam; the nonlinear optical crystal is bombarded with the first ion beam to obtain a primary processed crystal; the second heavy ions are accelerated to generate a second ion beam; the primary processed crystal is bombarded with the second ion beam to obtain a secondary processed crystal; and the secondary processed crystal is segmented to obtain the desired optical waveguide.
