Different models for calculating the optimum duty cycles to produce high blazed diffraction efficiency are compared. Blazed binary grating designs in a material with a refractive index n = 2 show theoretical diffraction efficiencies as high as η = 80%. In the semiconductor material silicon, which has a refractive index n = 3.4, theoretical diffraction efficiencies as high as η = 70% are predicted.||Funding Details:||Not applicable||Type of material:||Journal Article||Publisher:||Optical Society of America||Journal:||Applied Optics||Volume:||32||Issue:||22||Start page:||4276||End page:||4578||Copyright (published version):||1993 Optical Society of America||Subject LCSH:||Diffraction gratings
