Abstract
A theoretical study of the reflection spectra of multiple holographic expos ure distributed Bragg reflector gratings is presented. We will show that su ch a grating can exhibit a uniform reflection comb if the relative phases o f the superimposed gratings are well chosen. The tolerances on the optimal phases are of the order of 0.09 radians for six superimposed gratings to 0. 04 radians for ten gratings.
