Abstract
We proposed two apodization methods by controlling nonuniform spatial distribution of diffraction gratings for the transmission type of the holographic wavelength filter with photorefractive medium. Optimizing the intensity ratio and shapes of two writing beams, the improvement of transmission capacity is greatly improved to suppress the crosstalk.
