| Abstract: | The holographic gratings using DCG recordings material have the advantages of highdiffractive efficiency and low noise. Thanks to its significant Bragg diffractive effects, the reflectiveholographic gratings are much sensitive to the wavelength change, thus available for multi-exposiverecordings. In view of this, bi-peak value narrow band width holographic filter is studied using thedouble exposure recordings and special redeveloping techniques. This type of filter is comparativelyhigh in diffractive efficiency with bi-peak wave length at the same angle, and its peak value efficiencycan reach 87% and the band width is less than 10um, this filter has a wide and potential application inholographic image and light communications. This paper presents a discussion and analysis on thefilter's development and its spectrum features also. |
