Diffraction properties of transmission binary blazed grating

Huijun Zhou, Qu‐Quan Wang

Open publisher page 1 citations

Abstract

The properties of binary blazed grating were theoretically analyzed with finite-difference time -domain (FDTD) method. The diffraction efficiencies and diffraction angles of –1, 0, and +1 order for the grating varying with wavelength, grating structure, and the etch depth were studied when the incident angle was 30°. The numerical simulations revealed that the binary blazed grating presented high stability of diffraction efficiencies with wavelength shift.
