摘要：
Modal analysis of the reflective wideband grating with high efficiency of the negative first order in Littrow mounting is presented. The reflective grating consists of a highly reflective mirror and a transmission grating on the top. The modal analysis is carried out for TE polarization and it reveals that two modes are excited in the transmission grating. Using the two modes and ignoring the absorption of the mirror, a simple expression of diffraction efficiency of the reflective grating is derived and thus the grating depth to achieve high efficiency of the negative first order is obtained. The influence of duty cycle on the difference of effective indices of the two modes for different wavelengths is analyzed, which can explain the wideband behavior of reflective gratings. The modal analysis should be a useful tool for the design of high-efficiency wideband reflective gratings
