Abstract

The limited efficiency of diffractive optical elements is an important consideration in their design and application. These elements, fabricated using lithographic techniques, have very high theoretical diffraction efficiencies when analyzed using first-order scalar analysis. However, assumptions made in this scalar approach limit its accuracy for high frequency diffractive structures, such as those encountered in fast diffractive lenses. Fabrication limitations also reduce the physically achievable diffraction efficiency. This paper will discuss alternatives to the conventional scalar analysis technique and review how fabrication constraints can be incorporated into the design approach to realize improvements in diffraction efficiency.
