Abstract

The structure of transmission blazed binary gratings for optical limiting is designed with the form– birefringence theory. This kind of grating has subwavelength features, can imitate the transmission blazed grating effectively, and has higher efficiencies than a transmission blazed grating with a subwave length structure. The diffraction efficiencies are calculated and analyzed. For the normal incident light with 10.6 μm wavelength, the transmissivities for the designed grating at 0 ° deviation angle for TE and TM polarizations are 0.05% and 5.09%, respectively, which are basically identical to the results of the finite-difference time-domain method. The diffraction efficiencies of the first transmitted order for TE and TM polarizations are 93.95% and 83.88%, respectively.
