摘要：
Multilevel-grating array generators are discussed with an emphasis on the problems obtained in their fabrication. A fabrication error analysis procedure is presented which discuss the effects of mask alignment in the surface-relief profiles of an 8-beam array illuminator. Graphs and tables are presented showing the theoretical diffraction efficiencies for several two-dimensional grating array illuminators. Also considered are etch-depth errors. These results are simulated and evaluated numerically.
