Abstract

The equation describing refractive index distribution of GRIN structure with minimal aberrations is well known. But the main problem in technology is to obtain such profile caused by concentration distribution. In cylindrical coordinates concentration distribution is described by equation with Bessel functions which can be devided into power series. After suitable addition of its terms the equation similiar to one describing revractive index distribution. was received. Thus it was possible to compare their coefficients. So it was find that coefficients of refractive index distribution can be expressed by value T = D t/r²_° depending on technological process parameters. Knowing values of this coefficents, it is possible to optimalize the parameters of ion exchange technology in an aspect of manufacturing the GRIN structure with minimal aberrations.
