Abstract
In this paper, we have applied a perturbative expanding method to the hopping model, and studied the coupling effects of modulation depth between two pieces of photorefractive phase gratings stored in one point with an external applied dc field. The coupling equations of modulation depth and their steady solution have be derived. It has been found that the spatial -charge-filed of one of the two gratings is seriously affected by the modulation depth of other gratings.
