Paper Abstract

Gaussian distributed index change, in which its d.c. component keeps constant, is achieved by using the double exposure technique with a uniform phase mask and Gaussian UV laser beam. The reflected spectral sidelobes of the grating can be suppressed to below -30 dB and the related channel bandwidth is as narrow as expected.
