It is proposed that the apodization can be accomplished by use of the electrooptical effect of LiNbO 3 crystal based on the principle of the birefringence apodization.

Good performance of chirped fiber Bragg gratings obtained by asymmetrically one-side exposure apodization;

cosine-shaped and elliptical diaphragms are adopted to achieve the apodization of the instrumental function curve,and their respective theoretical instrumental resolutions are calculated.

Sectional apodization is used on chirped phase-shifted grating to obtain ap.
