Abstract
Holographic grating can be used widely in optical fields, especially in wavelength division multiplexer and optical fibre network. In this paper, a new kind of water resisting photopolymer which is sensitive to the red light of 632.8nm and green light of 514.5nm is made into double holographic grating by exposure twice. The resolution of this grating is above 4000line/mm. The principle of manufacture and technology of the new style grating is simple; it doesn't need the second treatment. The grating has many other merits, such as lower cost high diffraction efficiency, better stability and so on. Based on the study, the holographic grating can be used for wavelength-division demultiplexer for it is lower loss and narrow-band width.
