Abstract
A holographic dual-blazed grating with the period of 833 nm at ultraviolet-visible-near infrared was designed. To achieve higher and uniform diffraction efficiency, the grating profile was optimized by using rigorous coupled-wave analysis. The results show: when the two blaze angles of the dual-blazed grating, one within the range from 10 degree to 12 degree and the other one within the range from 26 degree to 32 degree respectively, the first-order diffraction efficiency is more than 30 percent within the wavelength from 0.25μm to 1μm. The holographic dual-blazed grating, one half with the blaze angle of 11 degree and the anti-blaze angle of 72 degree; and the other half with the blaze angle of 29 degree and the anti-blaze angle of 56 degree respectively, have been fabricated by improved holographic ion beam etching.
