This article introduces the near-field theory analysis and experiments of grating fabrication with phase masks. Under the optimal experiment condition, we fabricate the good quality optical fiber grating with center wavelength 1 546.9 nm and bandwidth 0.849 nm, while its power deviation is less than 1 dB and its time delay deviation is less than 30 ps. The dispersion of 10 Gb/s, 100 km G.652 optical fiber is compensated by the grating, and more than 98% dispersion is compensated.
