Abstract

Ray tracing is one of the methods to design diffractive optical elements. We included this theory to obtain two or four Gaussian beans from one Gaussian beam. The power distribution has been calculated by near field diffraction. First we considered one dimensional case and then the two dimensional case. Calculations are numerically solved using a computer program. The solutions for 1:2 branching are resolved for 1:4 branching in one-dimensional and two-dimensional formulations. The basic model for computing is that a given Gaussian beam is equally divided into two or four beams to produce two or four Gaussian beams with same beamwidth as the incident beam.
