Paper Abstract

The synthesis and fabrication of efficient holographic beamsplitters are considered in the paper. Various methods of computer design of two-dimensional binary and multistep holographic beamsplitters are described. The best efficiency achieved was 80 - 85%, the variations in beam intensities being less than 1%. A specially designed beamsplitter whose beam intensities vary from 0 to 7 is presented by way of example. A high-precision e-beam lithography technique was used to make beamsplitters for the visible spectral range. E- beam lithography allowed the realization of phase distribution with errors less than 2%. The effect of different kinds of phase errors on the beamsplitter efficiency and on variations of beam intensities is discussed. The value of allowable errors is determined. All these factors permitted us to make beamsplitters whose efficiency differs by just a few percent from the design efficiency.
