Abstract: PURPOSE:To easily obtain a desired refractive index distribution by forming a 2nd thin film on the exposed pattern formed on a 1st thin film and impressing a voltage from the 2nd thin film and the rear surface of a light transparent substrate and then reversing the directions of the impressed voltage to release the transplanted and diffused ions. CONSTITUTION:The 2nd thin film 4 is formed on the surface of the 1st thin film 2 and the surface 1 of the light transparent substrate exposed after the 1st thin film 2 is removed. While the light transparent substrate 1 is heated, the voltage is impressed between the 2nd thin film 4 and the rear surface of the light transparent substrate 1 to transplant and diffuse the 2nd ions contained in the 2nd thin film 4 through the part where the surface of the substrate 1 and the 2nd thin film 4 are in contact with each other to the light transparent substrate 1. The voltage is then impressed between the 2nd thin film 4 and the light transparent substrate 1 in this state at the polarity reverse from the polarity of the voltage impressed therebetween to release a part of the transplanted and diffused 2nd ions from the light transparent substrate 1. The desired refractive index distribution is easily obtd. in this way.
