Abstract :
In this paper, we examine the effect of applying bias phase on the design of diffractive optical elements for two colour far-field pattern formations. We also explain how critical the choice of the two wavelengths on the quality of the generated output patterns and the effect of changing the ratio of the wavelengths.
