Paper Abstract

Electromagnetic optimization is applied to four level surface relief gratings to obtain high diffraction effciencies over wide spectral ranges. The results are compared with the classical designs and proved superior. Significant improvements in the diffraction efficiency or independence of the incident wavelength can be obtained.
