【Abstract】 The tunability of a nonuniform reflection holographic filter was investigated theoretically and experimentally. It is shown that the reflection holographic filter has high optical density of peak wavelength, narrow half bandwidth, and very good tunability. The coupled wave theoretical model of uniform medium was compared with the model of nonuniform medium. It is identified that the theoretical results achieved by the nonuniform model is more coincident with the experimental results than the results gained by the uniform model.更多还原
