Paper Abstract

Geometric Optic analysis method is introduced into GL, two principle surface functions of GL are obtained. And from them, GL can be approximated to a thin lens just like gas lens. With light trail approaching, GL phase transission function can be found. Based on Fresnel diffractive theory, mode distribution of GL is obtained. Our optimal GL of non-curvature singularity and non-spherical has reference numbers: focus 20mm, aperture 8mm transition region 10mm. Incident light wavelength is 0.6328 μm. these parameters are substituted into GL field distribution, Matlab method is used to do analytical solution and intensity distribution. The theory model is similar to experiments.
