Abstract

Gratings are very important optical diffraction elements in fields of optical communication, optical information processing and optical precise measure, etc. But because of their structures, most common gratings will produce an unexpected loss of the input signal. Considering that, a new design of grating with many periodical micro isosceles prisms is proposed. Each periodical element of this new design looks like a combination of two periodical elements of a blazed grating, and the space frequency of the grating is small, so based on such an equivalent and according to scalar diffraction theory, the detailed expression of diffraction intensity of the prism grating is deduced and analyzed in this paper.
