【Abstract】 The transmission matrixes of Mach-Zehnder interferometer and birefringent interleaver were deduced, compared and analyzed. The use of staged birefringent to construct Fourier series and to improve the filtering characteristics of interleaver was proposed. The better filtering characteristics of staged birefringent were demonstrated by calculating and graphing. An applicable method for improving the filtering characteristic of birefringent interleaver was provided.更多还原
