Paper Abstract

Rigorous coupled-wave analysis is used to calculate the diffraction efficiency of THZ spectrum gratings. The ratios of grating periods and wavelengths and the ratios of grating depths and wavelengths of different type gratings are analyzed in this paper. Calculated results show that if the ratios of grating periods and wavelengths approximately equal to 1 and the grating depths greater than1.5, high diffractive efficiency of TE and TM polarization of symmetrical shape gratings will be got.
