摘要：
The diffraction properties for blazing -3 order of the perfectly conducting blazed gratings in the Littrow mounting under the polarized incident beam is investigated by numerical simulation. The diffractive electromagnetic fields for S and P polarized incident lights are calculated numerically using TDFD method. The field distribution of the electromagnetic field in the near groove area is analyzed, and the polarization dependency of diffraction efficiency is studied. The spectral characteristics in 1530-1566 nm range is given. It is proved that the efficiency for S polarized incident light is higher than that of P polarized one and it is not sensitive to the blazed angle. The spectral characteristic is flat within the fiber communication spectrum range.
